Description

When doing surgery or other operational tasks, it's nice to be able to have the .META. 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.
