* 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
Closes#2261

This patch adds the ability to discover newly added masters
dynamically on the master registry side. The trigger for the
re-fetch is either periodic (5 mins) or any registry RPC failure.
Master server information is cached in masters to avoid repeated
ZK lookups.
Updates the client side connection metrics to maintain a counter
per RPC type so that clients have visibility into counts grouped
by RPC method name.
I didn't add the method to ZK registry interface since there
is a design discussion going on in splittable meta doc. We can
add it later if needed.

* HBASE-23304: RPCs needed for client meta information lookup
This patch implements the RPCs needed for the meta information
lookup during connection init. New tests added to cover the RPC
code paths. HBASE-23305 builds on this to implement the client
side logic.
Fixed a bunch of checkstyle nits around the places the patch
touches.

Makes MergeTableRegionsProcedure do more than just two regions at a
time. Compatible as MTRP was done considering one day it'd do more than
two at a time.
Changes hardcoded assumption that merge parent regions are named
mergeA and mergeB in a column on the resultant region. Instead
can have N columns on the merged region, one for each parent
merged. Column qualifiers all being with 'merge'.
Most of code below is undoing the assumption that there are two
parents on a merge only.
This is a first cut at this patch. Implements hold fixing only
currently.
Add a fixMeta method to Hbck Interface.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java
Bug fix. If hole is on end of last table, I wasn't seeing it.
A hbase-server/src/main/java/org/apache/hadoop/hbase/master/MetaFixer.java
Add a general meta fixer class. Explains up top why this stuff doesn't
belong inside MetaTableAccessor.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java
Break out the filesystem messing so don't have to copy it nor do more
than is needed doing fixup for Region holes.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionFileSystem.java
Change behavious slightly. If directory exists, don't fail as we did
but try and keep going and create .regioninfo file if missing (or
overwrite if in place). This should make it idempotent. Can rerun
command. Lets see if any repercussions in test suite.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestMetaFixer.java
Add test.
