Oliver Walsh 4a7f3398f1 Add support for nova live/cold-migration with containers
Updates hieradata for changes in https://review.openstack.org/471950.
Creates a new service - NovaMigrationTarget. On baremetal this just configures
live/cold-migration. On docker is includes a container running a second sshd
services on an alternative port.
Configures /var/lib/nova/.ssh/config and mounts in nova-compute and libvirtd
containers.
