This issue breaks some tests. I opened HBASE-18627 and HBASE-18634 to fix. FYI [~stack]

> 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).
