ceph-defaults: fix ceph_uid fact on container deployments
ceph-defaults: fix ceph_uid fact on container deployments

Red Hat is now using tags[3,latest] for image rhceph/rhceph-3-rhel7.
Because of this, the ceph_uid conditional passes for Debian
when 'ceph_docker_image_tag: latest' on RH deployments.
I've added an additional task to check for rhceph image specifically,
and also updated the RH family task for ceph/daemon [centos|fedora]tags.
