Since the CloudStack virtual router was redesigned on version 4.6 it has been observed that the DHCP leases file is not persistent across network operations. This causes conflicts on guest VMs static IPs, causing these static IPs to not be renewed by the DHCP server running on isolated and VPC networks' virtual routers (dnsmasq). On stopping or destroying a VM, its dhcp/dns records are not removed from the virtual router causing ghost effects.

Offerings can co-exist where on does provide Security Grouping in the
network, but other guest Networks have no Security Grouping.
In V(X)LAN isolation environments the L2 separation is handled by V(X)LAN
and protection between Instances is handled by Security Grouping.
There are multiple scenarios possible where one network has Security Grouping
enabled because that is required in that network.
In the other network, but in the same zone it could be a choice to have
Security Grouping disabled and allow all traffic to flow.

With IPv6 we are not using DHCP to allocate addresses, but using
StateLess Address Auto Configuration (SLAAC) a Instance will calculate
it's own address based on the Router Advertisements send out by the
routers in the network.
This Advertisement contains the IPv6 Subnet in use in that subnet and
allows to calculate the stable Address the Instance will obtain based
on it's MAC Address.
The existing code is 'dead code' as it has been written, but was never
used by any production code.
SLAAC only works properly with subnets of exactly 64-bits large.

This PR adds the possibility to select a checkbox for the parameter bypassvlanoverlapcheck to the ajax request createNetwork. The checkbox was added for Guest Network as well as for the L2 Guest Network. For L2 Guest Network a backend check for the existence of the flag bypassvlanoverlapcheck was added.
This commit allows deploying VMs with a specific IPv4 address.
DirectPodBasedNetworkGuru does not support requesting a custom
IP-Address while creating a new NIC/Instance, throwing the following
error:
Error 530: Does not support custom ip allocation at this time:
NicProfile[0-0-null-null-null
Unknown macro: { "cserrorcode"}
Some use-cases prefer the ability to request the IPv4 address which the
Instance will get.
This implementation adds unit test cases to cover and it was manually
tested in Basic Networking. I can perform more tests if requested.
With earlier work in Basic Networking and the security group provider IPv6 is
supported and we can allow IPv6 to be supplied in networks with SG enabled.

This force stops old VRs when performing rolling restart with
cleanup=true. This will ensure that VRs are powered off quickly than
wait longer for the normal ACPI shutdown. During testing, it was found
on VMware where VM stops are slow compared to XenServer and KVM.

These boolean-return methods are named as "getXXX".
Other boolean-return methods are named as "isXXX".
Considering there methods will return boolean values, it should be more clear and consistent to rename them as "isXXX".

In integration work for CCS I found that the service call UserVmService.destroyVm(long uuid, boolean expunge) does not honour the expunge flag. I traced it down to the implementation VirtualMachineManagerImpl.destroy(String vmUuid, boolean expunge).
Testing: manual testing so far, testing will pose some crosscutting challanges as the behaviour and implementation are seperated by about five layers of abstraction.

Example: A VM that uses managed storage is stopped. The VM is then started on a different host in the same cluster. The Start operation fails.
To get around this issue, you must either start the VM up on the same host or on a host in a different cluster.
The reason is due to a slightly erroneous check in VolumeOrchestrator.prepare.
To solve this issue, we should be checking if the cluster ID changes, not if the host ID changes.
This introduces a new global setting `vm.configdrive.primarypool.enabled` to toggle creation/hosting of config drive iso files on primary storage, the default will be false causing them to be hosted on secondary storage. The current support is limited from hypervisor resource side and in current implementation limited to `KVM` only. The next big change is that config drive is created at a temporary location by management server and shipped to either KVM or SSVM agent via cmd-answer pattern, the data of which is not logged in logs. This saves us from adding genisoimage dependency on cloudstack-agent pkg.
The APIs to reset ssh public key, password and user-data (via update VM API) requires that VM should be shutdown. Therefore, in the refactoring I removed the case of updation of existing ISO. If there are objections I'll re-put the strategy to detach+attach new config iso as a way of updation. In the refactored implementation, the folder name is changed to lower-cased configdrive. And during VM start, migration or shutdown/removal if primary storage is enable for use, the KVM agent will handle cleanup tasks otherwise SSVM agent will handle them.

When a user shuts down their VM from the guest OS (and VM HA is enabled), the VM just powers itself back on. Our environment is on KVM hosts.
CloudStack does not know the difference between a VM failing or being shutdown from within the guest OS.
This is a major pain point for all our users - especially since they don't pay for VMs when they are shutoff. It is not intuitive for end-users to understand why they can't shutdown VMs from within the guest OS. Especially when they all come from (non-cloudstack) VMware and Hyper-V environments where this is not an issue.
However, if a host fails, we need VM HA to still work.
This PR that creates a configuration option "ha.vm.restart.hostup". With this option set to false, if CloudStack sees a VM shutdown out-of-band, but the host it was on is still online, then it won't power the VM back on. The logic is that since the host is online, it was most likely shutdown from the guest OS.
For when a host actually fails, standard VM HA logic takes over and powers on VMs (if they have VM HA enabled) if the host they were on fails.
If that "ha.vm.restart.hostup" option is true (the default to match current functionality), it works like always, and even in-guest shutdowns of VMs causes CloudStack to power back on the VM.
* Primary Storage count for an account does not decrease when a Data Disk is deleted
When a data disk is created and not attached in a running VM, the "deleteVolume" will not decrement the count for used primary storage in the VMs accounting information. The property that is not being decremented is called "primarystoragetotal"; this information can be retrieved via "listAccounts" API method.
Steps to reproduce this issue:
1 - Create an account, deploy a VM in it
2 - Check the primary storage count for the account with listAccounts API
3 - Create a data disk
4 - Check the primary storage count for the account with listAccounts API
5 - Delete the Data disk
6 - Check the primary storage count for the account with listAccounts API - It is the same as before deleting the data disk (it should not be the same as the value in step 2!)
* formatting and cleanups
* fix imports that were wrongly changed during rebase
This fixes config drive to use VM's user provided host-name instead of
the internal VM instance ID for hostname related config in both
cloudstack and openstack metadata bundled in the ISO.
