The ceph-mon-check pod only knew about the v1 port before, and didn't
have the proper mon_host configuration in its ceph.conf file. This
patchset adds knowledge about the v2 port also and correctly configures
the ceph.conf file. Also fixes a namespace hardcoding that was found
in the last ceph-mon-check fix.
