> Make it so we can bring up a Master in "maintenance mode". This is parse of
> master wal procs but not taking on regionservers. It would be in a state
> where "repair" Procedures could run; e.g. a Procedure that could recover meta
> by looking for meta WALs, splitting them, dropping recovered.edits, and even
> making it so meta is readable. See parent issue for why needed (disaster
> recovery).
