> Let this be umbrella issue for no-regions-on-master as default deploy (as it 
> was in branch-1).
> Also need to make sure we can run WITH regions on master; in particular 
> system tables with RPC short-circuit as it is now in hbase master.
> Background is that master branch carried a change that allowed Master carry 
> regions. On top of this improvement on branch-1, Master defaulted to carry 
> system tables only. No release was made with this configuration. Now we are 
> going to cut the 2.0.0 release, the decision is that hbase-2 should have the 
> same layout as hbase-1 so this issue implements the undoing of Master 
> carrying system tables by default (though the capability remains).
