Currently live_migration_flag is only written to nova.conf if Ceph is
in use. However, there may be other use cases using live migrations
where being able to override this is necessary. This commit introduces
a new variable called nova_libvirt_live_migration_flag and writes
live_migration_flag to nova.conf irrespective of whether Ceph is in
use. We also relocate nova_libvirt_disk_cachemodes and
nova_libvirt_hw_disk_discard in defaults/main.yml so that these
defaults sit with the other nova_libvirt defaults.
NOTE: We change the live_migration_flag defaults here to match nova's
defaults. Several Ceph resources suggest to use
VIR_MIGRATE_PERSIST_DEST however in my limited testing this did
not appear to be necessary. We can update the default or amend
it when using Ceph if we find that it is in fact necessary.
