* Admin API getLogEntries() for ring buffer use-cases: so far, provides balancerDecision and slowLogResponse
* Refactor RPC call for similar use-cases
* Single RPC API getLogEntries() for both Master.proto and Admin.proto

when neighbor is larger than average size
* add `testMergeEmptyRegions` to explicitly cover different
interleaving of 0-sized regions.
* fix bug where merging a 0-size region is skipped due to large
neighbor.
* remove unused `splitPoint` from `SplitNormalizationPlan`.
* generate `toString`, `hashCode`, and `equals` methods from Apache
Commons Lang3 template on `SplitNormalizationPlan` and
`MergeNormalizationPlan`.
* simplify test to use equality matching over `*NormalizationPlan`
instances as plain pojos.
* test make use of this handy `TableNameTestRule`.
* fix line-length issues in `TestSimpleRegionNormalizer`

* refactor how we use connection and async connection to rely on their access methods
* refactor initialization and cleanup of the shared connection
* incompatibly change HCTU's Configuration member variable to be final so it can be safely accessed from multiple threads.

Also fix three bugs:
* We were trying to delete non-empty directory; weren't doing
accounting for meta WALs where meta had moved off the server
(successfully)
* We were deleting split WALs rather than archiving them.
* We were not handling corrupt files.
Deprecations and removal of tests of old system.

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.

dynamic config changes. Having it to hbase-common makes it
accessible to all the other modules.

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).
