Review Comment:
The new MobFileCleanerChore is not the same as the old one. The main cleanup
is done by the RSMobFileCleanerChore running on each RS, cleaning up mob files
created by regions hosted on that RS. This should cover most of the usecases.
But I still had to run a restricted version of the old MobFileCleanerChore
to clean up after mobs made by now-archived regions, because to make sure those
are not referenced anymore every hfile have to be checked.
