Review request for hbase and stack.
Summary
-------
This is patch from Jeff Whiting. I then did little bits of polish and slim
down of the unit test.
I uncovered very odd coupling of LogsCleaner being instantiated within
ServerManager, though we don't use it there and it doesn't use SM. So that's
refactored out into HMaster and is started up/shut down with
start/stopServiceThreads().
Changes from Jeff patch:
- Moved pulling maxSkew from config into constructor rather than doing it on
each call
- Cleaned up the logging message a bit and changed from DEBUG to WARN
- HRS side, use EnvironmentEdgeManager rather than System.currentTimeMillis
directly
- Changes test to operate directly on ServerManager. I had to do a bit of
refactoring of ServerManager to get this to work and it's nothing something
anyone new would have pulled the trigger on (moving stuff into another class
instead of the weird unnecessary coupling to ServerManager).
This addresses bug HBASE-3168.
