Writing a test for this is tricky. There is enough coverage for
functional tests. Only concern is performance, but there is enough
logging for it to detect timed out/badly performing sync calls.
Additionally, this patch decouples the ZK event processing into it's
own thread rather than doing it in the EventThread's context. That
avoids deadlocks and stalls of the event thread.

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.

This utility is useful for any module that wants to detect
dynamic config changes. Having it to hbase-common makes it
accessible to all the other modules.

This is needed for the hbase-native-client to compile. Also ships
the includes in the assembly tar.

Simplify the new user experience shipping a configuration that enables
a fresh checkout or tarball distribution to run in standalone mode
without direct user configuration. This change restores the behavior
we had when running on Hadoop 2.8 and earlier.
Patch for master includes an update to the book. This change will be
omitted when backporting to earlier branches.

Move the random free port generate back into hbasecommontestingutility
from hbasetestingutility.
Add a create simple kdc server utility that will start a kdc server and
if a bindexception, create a new one on a new random port in hbase-common.
Add new BoundSocketMaker helpful when trying to manufacture
BindExceptions because of port clash.
Change thrift and http kdc tests to use this new utility (removes
code duplication around kdc server setup).
* Reorganize MOB compaction tests for more reuse.
* Add tests for mob compaction after snapshot clone operations
* note the original table used to write a given mob hfile and use that to find it later.

Master rpc server end point doesn't bind to localhost's
IP address by default. Instead, it looks up the hostname and
binds to the endpoint to which it resolves. MasterRegistry should
do the same when building the default server end point to talk to.
