table quickly cleaned of split parents. The CatalogJanitor already has controls baked in (currently
used in unit tests), I think we should expose this the same way we do with the balancer, that
is:
>  - start
>  - stop
>  - request a run
> A client would need to go through HBaseAdmin, and shell commands need to be created.
