Mohammed Naser 8f0a154138 fix(nova): add default live_migration_inbound_addr
At the moment, if live_migration_inbound_addr is not defined it
will default to the hostname of the hypervisor which requires
DNS in order to work properly.

DNS can be complicated and it is possible that an environment
might not have it, so it makes sense to default to grabbing the
default route interface to do live migrations over in order
to allow live migrations when DNS is not setup.
