Configure the Ceph rgw daemon completely from the operator a la the recent changes to the Ceph mon, mgr, and mds operators. Create the rgw deployment or daemonset first, and then create the keyring secret for the object store with its owner reference as the corresponding deployment or daemonset. When the replication controller is deleted, the secret is also deleted. The RGW's mime.types file is now stored in a configmap with a different file created for each object store. This is primarily just a means to get the mime.types file into the rgw pod, but the added benefit is that the administrator can modify the configmap, which could reduce susceptibility to file type execution vulnerabilities (worst case).
