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.

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.

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.

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.

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.

VMware router will be rebooted based on #2794, per current config
the VRs on reboot will go through fsck checks slowing down the deployment
process by few seconds. This will ensure that fsck checks are done
on every 3rd boot of the VR. The `4` is used because 1st boot is done
during the build of systemvmtemplate appliance.
Add upgrade path for a new 4.11.2 systemvmtemplate.
Other changes:
- Add support for XS 7.5 Fixes#2834.
- Reboot VR only if mgmt gw is not pingable on vmware.
- Enable passive ftp by enabling nf_conntrack_helper. This is change in behaviour since linux 4.7

* CLOUDSTACK-9473: storage pool capacity check when volume is resized or migrated
Storage pool checker is not being called on resize and migrate volume.
This may lead to allocated percentage of storage above 100%.
Setup:
1 VMware cluster with 2 Hosts.
Executed Steps:
Applied the following global settings:
storage.overprovisioning.factor = 1
pool.storage.allocated.capacity.disablethreshold = 1
pool.storage.capacity.disablethreshold = 1
Restarted management server
Executed Resize and migrate pool and Observed that Storage pool checker is not performed on resizeVolume and migrateVolume.
Result:
Root cause analysis shows storage pool checker is not called when doing migration and resizing.

In the UI, when Setting up a recurring snapshot for a volume and clicking 'Add', the newly added scheduled snapshot entry is not displayed in the 'Scheduled Snapshots' table. Also, the 'Keep' input field does not limit the length of a number that can be added. This causes the API not return an error that the value is invalid.
After adding a recurring snapshot, it must display in the 'Scheduled Snapshots' table. The 'Keep' input field must restrain a user from entering too large of a number.
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.
Arping command in virtual-router was called anyway on python code.
on file: merge.py
line 239, in this code : "dp['gateway'] ='None' ''
later on CsAddress.py line 303
if 'gateway' in self.address:
self.arpPing()
This string 'None' makes if steatement always be true
the solution on #2806 makes dp['gateway'] =''
Cannot be None type because there is a string operation later on code.

[VMware] VM is not accessible after migration across clusters.
Once a VM is successfully started, don't delete the files associated with the unregistered VM, if the files are in a storage that is being used by the new VM.
Attempt to unregister a VM in another DC, only if there is a host associated with a VM.
This closes#556
