CLOUDSTACK-9062: Improve S3 implementation.The S3 implementation is far from finished, this commit focuses on the bases.
- Upgrade AWS SDK to latest version.
- Rewrite S3 Template downloader.
- Rewrite S3Utils utility class.
- Improve addImageStoreS3 API command.
- Split various classes for convenience.
- Various minor improvements and code optimizations.
A side effect of the new AWS SDK is that it, by default, uses the V4 signature. Therefore I added an option to specify the Signer, so it stays compatible with previous versions.
Please review thoroughly, both code inspection and (automated) integration tests. Currently no integration tests are available specifically for S3. Therefore the implementation is needed to be tested manually, for now...
What I tested:
- Greenfield install -> will download latest systemvm template automatically to S3.
- Upload a template/iso
- Download a template/iso
- Restart of management server -> list available templates -> doesn't download them again if available.

CLOUDSTACK-9067 - As I developer I want to remove all the unused router-shell scripts from ACSThis PR removes the unused shell scripts that were present in the ACS project. Those script were replaced by the.
Some of the scripts are used by the HyperV Resource, which were hardcoded. I took the opportunity to use the Java constants over there as well, so the next one touching the code will know they exist and won't hardcode anything.
The following task were applied:
* Remove the shell files and the Java constants that were mapping them;
* Apply the use of the Java constants to the HyperV Resource class;
* Wrap the String.format() method in the StringUtils so we can test the changes in the HyperV Resource class.
The last point was added because I do not have a HyperV test environment. Hence, I wanted to make sure the tiny code I changed is covered at least by unit tests.

CLOUDSTACK-8956: NSX/Nicira Plugin does not support NSX v4.2.1JIRA Ticket: https://issues.apache.org/jira/browse/CLOUDSTACK-8956
### Description of the problem:
Prior to version 4.2. Nicira/VmWare NSX used a variation of Open vSwitch as means of integrating SDN into hypervisor layer. Cloudstack NiciraNVP plugin was written to support OVS as a bridge to NSX.
In version 4.2 VMware introduced NSX vSwitch as a replacement for OVS in ESX hypervisors. It is a fork of distributed vSwitch leveraging one of the recent features of ESX called opaque networks. Because of that change the current version of NiciraNVP plugin doesnt support versions of NSX-MH above 4.2 specifically in Vsphere environment. Proposed fix will analyze a version of NVP/NSX API and use proper support for ESX hypervisors.
vSphere hypervisor mode operations when NV is deployed onto NSX managed network changes:
* Current mode. A portgroup = UUID of CS VM NIC is created on a local standard switch of the Hypervisor where VM is starting. VM nic is attached to that port group.
* New mode. No additional port group is created on a HW. No port group cleanup is needed after VM/NIC is destroyed. VM is attached to 1st port group having the following attributes:
** opaqueNetworkId string "br-int
** opaqueNetworkType string "nsx.network"
If portgroup with such attributes is not found a deployment should fail with exception.
### VMware vSphere API version from 5.1 to 5.5:
Since vSphere API version 5.5, [OpaqueNetworks](https://www.vmware.com/support/developer/converter-sdk/conv55_apireference/vim.OpaqueNetwork.html) are introduced.
Its description says:
> This interface defines an opaque network, in the sense that the detail and configuration of the network is unknown to vShpere and is managed by a management plane outside of vSphere. However, the identifier and name of these networks is made available to vSphere so that host and virtual machine virtual ethernet device can connect to them.
In order to connect a vm's virtual ethernet device to the proper opaque network when deploying a vm into a NSX managed network, we first need to look for a particular opaque network on hosts. This opaque network's id has to be **"br-int"** and its type **"nsx.network"**.
Since vSphere API version 5.5 [HostNetworkInfo](https://www.vmware.com/support/developer/converter-sdk/conv55_apireference/vim.host.NetworkInfo.html#opaqueNetwork) introduces a list of available opaque networks for each host.
If NSX API version >= 4.2 we look for a [OpaqueNetworkInfo](https://www.vmware.com/support/developer/converter-sdk/conv55_apireference/vim.host.OpaqueNetworkInfo.html) which satisfies:
* opaqueNetworkId = "br-int"
* opaqueNetworkType = "nsx.netork"
If that opaque network is found, then we need to attach vm's NIC to a virtual ethernet device which support this, so we use [VirtualEthernetCardOpaqueNetworkBackingInfo](https://www.vmware.com/support/developer/converter-sdk/conv55_apireference/vim.vm.device.VirtualEthernetCard.OpaqueNetworkBackingInfo.html) setting:
* opaqueNetworkId = "br-int"
* opaqueNetworkType = "nsx.netork"

sysctl: don't modify /etc/sysctl.confTo configure firewall rules, CloudStack modifies `/etc/sysctl.conf` and
execute those modifications. This may be harmful for several reasons:
1. `/etc/sysctl.conf` may be managed by some configuration management
system. Such a system will constantly restore the previous version.
2. `/etc/sysctl.conf` may contain additional properties that have been
changed later by some system administrator (for example, once a
firewall has been configured, forwarding may have been activated
while it is disabled in `/etc/sysctl.conf`). Executing the file
again at a later time may disrupt the system.
3. Entries are added again and again. `/etc/sysctl.conf` will contain
the same directives repeated several times.
Using a configuration file is not needed as `sysctl` is able to directly
modify sysctl values with `-w` flag.

Guys, can you review it? things need to be discussed:
(1) this supports KVM/QCOW2 only. Anyone want to implement for other Hypervisor/format ?
(2) The original data volume (on primary storage) will be removed.
(3) The script uses the default timeout in libvirtComputingResource. Do we need to add one in global configuration (like copy.volume.wait or backup.snapshot.wait, create.volume.from.snapshot.wait)
(4) In scripts/storage/qcow2/managesnapshot.sh, I use "qemu-img convert -f qcow2 -O qcow2" to copy the snapshot from secondary to primary (hence there is no base image file), instead of "cp -f", this is because convert is faster than cp in my testing.

Based on the way HV check is present in the scale VM API, had to explicitly put simulator related check to allow support. The ideal way would be to remove all these HV specific check from code and made them some configuration (by putting them in hypervisor_capabilities table in DB). But that will be a bigger effort outside the scope of this PR.

Default to notify only script to handle non-CLVM/QCOW cases.This relates to [CLOUDSTACK-8732](https://issues.apache.org/jira/browse/CLOUDSTACK-8732)
Before this commit the call to `getResizeScriptType` would throw an exception (earlier versions returned `null`, which was fine) - this caused the RBD case to fail. By changing the default to notify only we fix the case for any non-CLVM and non-QCOW cases, too.
This is RBD for now, but this should extend to new storage types supported by Libvirt natively in future.
This is my first attempted contribution: I can see a case for adding RBD logic to the actual getResizeScriptType call, too, but I felt that putting it `LibvirtResizeVolumeCommandWrapper.java` kept the special-casing of RBD (and comments about that) in one place.
### Caveat:
With Libvirt 1.2.2 this actually doesn't do the right thing - but it does do what the documentation *says* should be the right thing, so I'm going to test if this is a Libvirt bug which is fixed in a later version.
(To make it work I need to execute something like:
virsh blockresize --path vda --size 100G i-7-44-VM
where vda is the path as far as the *guest* is concerned, and not an `rbd/` path - which *should* work, but doesn't.)

CLOUDSTACK-8443: Support CentOS 7 as KVM hypervisorThis adds support for CentOS 7 as a KVM hypervisor. As discussed in the Jira issue, the root cause of the issue was the `cloudstack-setup-agent` script that added this line to `/etc/libvirt/qemu.conf`:
`cgroup_controllers=["cpu"]`
On CentOS 6 this 'works', but since by default no cgroups are mounted, this setting is ignored by `libvirtd`. On CentOS 7 is does not work, because the `cpu` and `cpuacct` are 'co-mounted'. This simpy means you cannot use one without the order. The config line above instructs `libvirtd` to only use the `cpu` cgroup, which it can't.
There was code added to make sure the `cpu` cgroup was not co-mounted. It did this with a shell script, but after a reboot it was gone. It wasn't reliable and not even a solution at all. I went ahead and removed the code, because the co-mounted cgroups work fine. The real issue was the config line we put in `/etc/libvirt/qemu.conf` so much better to fix that instead.
The default for `libvirtd` is to use only cgroups that are mounted. When you remove the 'cgroup_controllers' line, the default kicks in. According to the `qemu.conf` file, the default is:
`cgroup_controllers = ["cpu", "devices", "memory", "blkio", "cpuacct", "net_cls"]`
Then again, if it's not mounted, it's not used. So, that's a nice way to control it.
This works just fine for both RHEL/CentOS 6 and RHEL/CentOS 7.
Along the debugging, I came across some small issues here and there which I also fixed in this PR.
If you test this, be sure to build RPMs from this branch and install those on the KVM hypervisor.
At Schuberg Philis we run KVM hypervisors on CentOS 7 for months with these fixes. Now I took the time to fix the issues in CloudStack, rather than work around them.
@bhaisaab @karuturi could you please review this? Thanks!
Please note:
The next step is to fix CLOUDSTACK-8625 (Systemd profile for KVM Agent) as currently a sysvinit script is still used. Although it works, we do not have any systemd benefits. As it is a separate issue, I'll try to address it in a separate PR.

CLOUDSTACK-8443: don't try to fix co-mounted cgroups
Signed-off-by: Remi Bergsma <github@remi.nl>
This setting works on CentOS 6 / RHEL 6 but does nothing, as
"cpu" cgroup is not mounted. On CentOS 7 / RHEL 7 systemd does
mount cgroups and "cpu" is co-mounted with "cpuacc". Hence, if
we specify "cpu" then this results in an error because it can
only use them both, or none.
By removing the setting, we rely on the default of qemu, which
is:
cgroup_controllers = ["cpu", "devices", "memory", "blkio", "cpuacct", "net_cls"]
Only if they are really mounted, they will be used. So, this will
work on both version 6 and 7.
The 'fix script' didn't work well, as after a reboot you'd still have qemu
throwing errors. Now we can handle the co-mountedcgroups.

Removed duplicate code in CitrixResourceBase and its subclassesRemoved unnecessary duplicated code by having the body of the getPatchFiles method only in the CitrixResourceBase superclass. Given that all of its implementations consisted of the same code except for the path which contains the necessary file for that implementation. An abstract method getPatchFilePath was created in the CitrixResourceBase superclass so that each implementation may return the path containing the specific file needed by that implementation.
Test cases were created for each implementation, simple as they may be. One assert is made to verify that the path returned by each implementation corresponds to the path that was previously specified on each getPatchFiles implementation.

Fixed VmWareGuru.java after Nic.java refactor.
See issue CLOUDSTACK-8736 for ongoing effort to clean up network code.
@cristofolini comments:
Removed unnecessary duplicated code by having the body of the
getPatchFiles method only in the
CitrixResourceBase superclass. Given that all of its implementations
consisted of the same code
except for the path which contains the necessary file for that
implementation. An abstract method
getPatchFilePath was created in the CitrixResourceBase superclass so
that each implementation may
return the path containing the specific file needed by that
implementation.
Test cases were created for each implementation, simple as they may be.
One assert is made to verify
that the path returned by each implementation corresponds to the path
that was previously specified
on each getPatchFiles implementation.
