Description

This probably means

- shutting down current instances, resetting cluster membership
- throwing out journals (or maybe not; but that's a separate feature)
- restarting cluster in single-mds, maybe with repair mode flag

see mds_reset branch.

Still need a process to reset the individual mds instances. This should:
- advance the journal header info to a new, unused region.
- do, or journal a single event that (on replay) will,
- update the mds inotable to avoid reusing ino's.
- zero out the mds session table.
