libceph: embed ceph connection structure in mon_client
A monitor client has a pointer to a ceph connection structure in it. This is the only one of the three ceph client types that do it this way; the OSD and MDS clients embed the connection into their main structures. There is always exactly one ceph connection for a monitor client, so there is no need to allocate it separate from the monitor client structure. So switch the ceph_mon_client structure to embed its ceph_connection structure. Signed-off-by: Alex Elder <elder@inktank.com> Reviewed-by: Sage Weil <sage@inktank.com>
