libceph: embed ceph messenger structure in ceph_client
(cherry picked from commit 15d9882c336db2db73ccf9871ae2398e452f694c)
A ceph client has a pointer to a ceph messenger structure in it.
There is always exactly one ceph messenger for a ceph client, so
there is no need to allocate it separate from the ceph client
structure.
Switch the ceph_client structure to embed its ceph_messenger
structure.
