CFME: Use cluster_hostname if cluster_public_hostname isn't available

The CFME 'automatically add provider' playbook would fail if
openshift_master_cluster_public_hostname was not defined in the
inventory. Now we use that value if it is available, and fallback to
using the masters 'cluster_hostname' otherwise.
