Fix CatalogTracker. Make it use Procedures doing clean up of Region data on split/merge. Without these changes, ITBLL was failing at larger scale (3-4hours 5B rows) because we were splitting split Regions.
Added a bunch of doc. on Procedure primitives. Added new region-based state machine base class. Moved region-based state machines on to it. Found bugs in the way procedure locking was doing in a few of the region-based Procedures. Having them all have same subclass helps here. Added isSplittable and isMergeable to the Region Interface. Master would split/merge even though the Regions still had references. Fixed it so Master asks RegionServer if Region is splittable. Messing more w/ logging. Made all procedures log the same and report the state the same; helps when logging is regular. Rewrote TestCatalogTracker. Enabled TestMergeTableRegionProcedure. Added more functionality to MockMasterServices so can use it doing standalone testing of Procedures (made TestCatalogTracker use it instead of its own version).
