This one surfaced as a flake test but turns out to be a legit bug
in FIFOCompaction code. FifoCompaction does not check if an empty
store file is already being compacted by an in-flight compaction
request and still enqueues. It can potentially race with a running
compaction (as in this test case, see jira for the exact exception).
Fixes the edge case and cleans up the test code a bit.

Simplify our Normalizer story to have just a single, configurable
implementation.
* fold the features of `MergeNormalizer` into
`SimpleRegionNormalizer`, removing the intermediate abstract class.
* configuration keys for merge-only features now share a common
structure.
* add configuration to selectively disable normalizer split/merge
operations.
* `RegionNormalizer` now extends `Configurable` instead of creating a
new instance of `HBaseConfiguration` or snooping one off of other
fields.
* avoid the extra RPCs by using `MasterServices` instead of
`MasterRpcServices`.
* boost test coverage of all the various flags and feature
combinations.

The PLAIN mechanism test added in the Shade authentication example has
different semantics than GSSAPI mechanism -- the client reports that the
handshake is done after the original challenge is computed. The javadoc
on SaslClient, however, tells us that we need to wait for a response
from the server before proceeding.
The client, best as I can see, does not receive any data from HBase;
however the application semantics (e.g. throw an exception on auth'n
error) do not work as we intend as a result of this bug.
Extra trace logging was also added to debug this, should a similar error
ever happen again with some other mechanism.

JMXCacheBuster resets the metrics state at various points in time. These
events can potentially race with a master shutdown. When the master is
tearing down, metrics initialization can touch a lot of unsafe state,
for example invalidated FS objects. To avoid this, this patch makes
the getMetrics() a no-op when the master is either stopped or in the
process of shutting down. Additionally, getClusterId() when the server
is shutting down is made a no-op.
Simulating a test for this is a bit tricky but with the patch I don't
locally see the long stacktraces from the jira.
