Currently, if you try to start an on-demand container using the
"utilscli dbutils" command, on a site where remote backup has been
disabled, then the on-demand container will get a container create error
saying that it cannot read the backup-user secret (which does not get
generated when remote backup is disabled).
This patchset disables the reading of variables from the backup-user
secret (aka, the rgw secret) if remote backup is disabled.
