[ceph-client] Fix ceph.conf update job labels, rendering

This change fixes two issues with the recently introduced [0] job that
updates "ceph.conf" inside ceph-client-etc configmap with a discovered
mon_host value:

1. adds missing metadata.labels to the job

2. allows the job to be disabled
   (fixes rendering when manifests.job_ns_client_ceph_config = false)
