This change adds an openstack-support-rook zuul job to test
deploying Ceph using the upstream Rook helm charts found in the
https://charts.rook.io/release repository. Minor changes to the
storage keyring manager job and the mon discovery service in the
ceph-mon chart are also included to allow the ceph-mon chart to be
used to generate auth keys and deploy the mon discovery service
necessary for OpenStack.
