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.

Incorrect diskpath information was being sent to virsh blockresize, so the block device size was never refreshed to reflect the new disk size.

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".

Ubuntu 14.04 will go EOL in April 2019. With a new CloudStack
release close to that date we can drop support for this Ubuntu
version and the master branch of CloudStack.
Ubuntu 16.04 (Xenial) and 18.04 (Bionic) both have systemd and
more recent Java versions which make it easier to run the CloudStack
KVM Agent on them.
In addition libvirt and Qemu are more up to date with features
which allow VMs to run better.
Yet to be implemented features in KVM can also leverage the newer
version of Qemu and libvirt without the need of taking older
version of them into account.
