The operator schedules all the mons at the same time, then
serially starts each of the mons. If the operator was restarted
or otherwise failed before all the mons were started, the next
reconcile will schedule new mons again and ignore the scheduling
that was already computed. Since the last mon running is always
expected to be in quorum, we can reset the maxMonId to be
the highest mon currently created.
