Change the timeouts of the TEST_mon_add_to_single_mon tests to be 120
seconds. They have value to guard against blocking forever. The exact
timing does not matter as long as the operation completes.
When a timeout is too short, it will create false negatives when running
on slow machines. It could be argued that being too generous with
timeout in general may hide problems. But not in this specific case.

this change removes the step to "ceph mon add" before starting a new
monitor. because the existing leader will start an election at seeing
the MMonJoin message sent by the new joiner, after the quorum is
archieved, the monmap will be updated with the new monitor.
so, "ceph mon add" is not necessary to add a new monitor.
moreover, this command will be blocked until a new quorum is formed,
and the proposed monmap is accepted. but in case of adding a monitor
to a single monitor cluster, the leader will wait until at least two
of the monitors reply to it. apparently, this does not happen unless
the new monitor starts. so from the user's point of view, this
command hangs until timesout, if he/she does not start the mon.b
beforehand. but this is an expected behaviour.
so, to avoid this confusion and simplify the steps to add a new
monitor. we'd better simply remove this "ceph mon add" step.

Not bothering with this for non-namespaced object iterator
or the C interface. Expect to replace this with
the new-style pgls, so just exposing it enough for
cephfs-data-scan to touch the new osd-side pgls filtering
