[ceph-mon] Change configmap names to be based on release names

This change makes the ceph-mon configmap names dynamic based on
release name to match how the ceph-osd chart is naming configmaps.
The new ceph-mon post-apply job needs this in some cases in order
not to have conflicting configmap names in separate releases.
