mon: change how we handle removed_ranks

when a new monitor joins, there is a chance that
it will recive a monmap that recently removed
a monitor and ``removed_rank`` will have some
content in it. A new monitor that joins
should never remove rank in peer_tracker but
rather call ``notify_clear_peer_state()``
to reset the `peer_report`.

In the case when it is a monitor that
has joined quorum before and is only 1
epoch behind the newest monmap provided
by the probe_replied monitor. We can
actually remove and adjust ranks in `peer_report`
since we are sure that if there is any content in
removed_ranks, then it has to be because in the
next epoch we are removing a rank, since every
update of an epoch we always clear the removed_ranks.

There is no point in keeping the content
of ``removed_ranks`` after monmap gets updated
to the epoch.

Therefore, clear ``removed_ranks`` every update.

When there is discontinuity between
monmaps for more 1 epoch or the new monitor never joined quorum before,
we always reset `peer_tracker`.

Moreover, beneficial for monitor log to also log
which rank has been removed at the current time
of the monmap. So add removed_ranks to `print_summary`
and `dump` in MonMap.cc.
