Improved performance on creating VM for KVM virtualization.
On a huge hosts every "ifconfig | grep" takes a lot of time (about 2.5-3 minutes on hosts with 500 machines). For example: ip link show dev $vlanDev > /dev/null is faster than ifconfig |grep -w $vlanDev > /dev/null. But using ip command is much better. Using this patch you can create 500s machine in 10 seconds. You don't need slow ifconfig prints anymore.
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.

Windows has support for several paravirt features that it will use when running on Hyper-V, Microsoft's hypervisor. These features are called enlightenments. Many of the features are similar to paravirt functionality that exists with Linux on KVM (virtio, kvmclock, PV EOI, etc.)
Nowadays QEMU/KVM can also enable support for several Hyper-V enlightenments. When enabled, Windows VMs running on KVM will use many of the same paravirt optimizations they would use when running on Hyper-V.
A number of years ago, a PR was introduced that added a good portion of the code to enable this feature set, but it was never completed. This PR enables the existing features. The previous patch set detailed in #1013 also included the tests.
By selecting Windows PV, the enlightenment additions will be applied to the libvirt configuration. This is support on Windows Server 2008 and beyond, so all currently supported versions of Windows Server.
In our testing, we've seen benchmark improvements of around 20-25% running on Centos 7 hosts and it is also supported on Centos/RHEL 6.5 and later. Testing on Ubuntu would be appreciated.
Install any additional plugin jars in the lib directory to be picked up
by the classpath builder, otherwise one has to manually add the jar
to /etc/default/cloudstack-management after installation. This fixes
the issue for `mysql-ha` plugin.

This fixes an issue for systemvms (CPVM and SSVM) on VMware, as eth0
is not programmed (link-local) the networking.service fails to start
which is a dependency for cloud-postinit service. When cloud-postinit
service fails to start/run, it fails to start the agent (cloud) process.
This fixes the smoketest failures we saw in case of VMware 6.5 with
4.11.

maven command for finding current version might need to download packages and without batch mode it will end in variable. Added '-B' to enable batch mode.
Unify checksum API output for templates and ISOs: not list the checksum algorithm on:
KVM direct downloads
On in progress normal template downloads. The algorithm is shown on the listtemplates API, but after it is downloaded it is not shown anymore.
This adds a global setting for admins who may not want the rolling
restart of routers or are seeing any issues around it. In future, this
setting may be removed.

When agent is stopped, don't allow reconnection. Previously this would
send a shutdown command to the management server which would put the
host state to Disconnected but then agent's reconnection logic may kick
in sometimes which would connect the agent to the management server
but then the agent process would terminate causing the host to be
put in Alert state (due to ping timeout or it waiting too long).
This fixes the issue by ensuring that when the agent is stopped, it
does not reconnect to the management server.

The idea is to create a property in /etc/defaults/cloudstack-agent that
can be enabled/disabled (uncommented/commented) to control the enabling
of Java remote debug in CloudStack's JVM.
This tries to provide a threshold based fix for #2873 where swappinness of VR is not used until last resort. By limiting swappiness unless actually needed, the VR system degradation can be avoided for most cases. The other change is around not starting baremetal-vr by default on all VRs, according to the spec https://cwiki.apache.org/confluence/display/CLOUDSTACK/Baremetal+Advanced+Networking+Support only vmware VRs need to run it and that too only as the last step of the setup/completion, so we don't need to run it all the time.

This fixes#2719 where private gateway IP might be incorrectly
programmed on a guest network nic. The VR would now check ipassoc
requests by mac addresses than provided nic/device id in case they are
wrong.
The root cause is that the device id information is lost when aggregated
commands are created upon starting of a new VPC VR, without the correct
device id in ip_associations json it mis-programs the VR.

This update changes how the languages are shown on the UI's login page. Previously all languages were shown in the current language of the login page. This meant for instance, that a Japanese speaker would have to know English to find their language. Likewise if the language had been changed, a German speaker might need to speak Korean in order to find their language.
Therefore the UI has been altered to always show the name of each language in the appropriate language.
This fixes the default RootCA provider implementation to initiate
and issue certificate for mgmt server on startup for all the IP addresses
on the default nic of that host.

We see a suspicious continuous increase in memory usage. Kind of looks like a memory leak.
One thing noted during debugging is that flask is started in debug mode. This is not best practice for a production system.
This makes the agent logrotate config to `noreplace` so on upgrade
any changes to the file are not lost.

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".
