Jimmy McCrory 1b0d2d3aa2 Set default for physical_host if it's undefined
physical_host is a host variable created by openstack-ansible's dynamic
inventory. When using this role outside of an integrated OSA deployment
it wouldn't be expected to be set. Fallback on using inventory_hostname
when physical_host is undefined.
