Review request for hbase, stack, Karthik Ranganathan, and Kannan Muthukkaruppan.
Changes
-------
Moved stuff out of the constructor and into run(). Now all three masters start
but then it freezes on something else.
Pardon the "\n\n\n DEBUG! \n\n\n" :)
Summary
-------
To really be able to unit test the new master properly, we need to be able to
have multiple masters running at once within a single logical cluster.
Also exposes methods to get the currently active master and can access each
individually in the same way that it's done for multiple RS.
This is mostly duplicating what we do for RS but for masters.
This addresses bug HBASE-3053.

Testing
-------
Untested but compiles. This is first go at a patch. I'm going to work on
writing a new unit test that uses this next.
Thanks,
