Thales Elero Cervi 310f677d29 Move live-migration traffic to cluster-host-net 
This change updates the application plugins in order to ensure that all
libvirt/live-migration related traffic is happening through the
cluster-host-network. Currently most of the libvirt/live-migration
addresses are being solved through INADDR_ANY (0.0.0.0), and this route
resolution will vary between AIO, routes to oam-network, and Worker,
routes to mgmt-network. Both resolutions are not correct since the
correct network for such traffic should be the cluster-host-network.
Actually, current platform firewall will block any traffic through not
allowed oam-network ports.

The goal will be achieved by setting to the node's cluster-host IP:
* libvirt listen_addr
* nova.conf "live_migration_inbound_addr"

It is important to notice that in the current version of the
openstack-helm nova helm chart, there is a problem with
nova-compute-init.sh for this use case of ours, so an openstack-helm
patch was required to fix it.

Code that was previously implemented only for the Nova plugin and is now
required by the Libvirt plugin, was moved to the parent OpenStack class.

TEST PLAN:
PASS - Build stx-openstack application
PASS - Apply the application to an AIO-DX system
PASS - "$ sudo netstat -ltnp | grep <libvirtd pid>" to ensure that
       libvirtd is listening on the correct cluster-host-net IP
PASS - Verify that the nova-compute.sh script was populated correctly
PASS - Test a VM live-migration on the controller+worker node
PASS - Verify that live_migration data in LibvirtLiveMigrateData has the
       correct cluster-host-net IP address in its "target_connect_addr"
PASS - Apply the application to a Standard system
PASS - "$ sudo netstat -ltnp | grep <libvirtd pid>" to ensure that
       libvirtd is listening on the correct cluster-host-net IP
PASS - Verify that the nova-compute.sh script was populated correctly
PASS - Test a VM live-migration on the worker node
PASS - Verify that live_migration data in LibvirtLiveMigrateData has the
       correct cluster-host-net IP address in its "target_connect_addr"
