* 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.

* HBASE-23257: Track clusterID in stand by masters (#798)
This patch implements a simple cache that all the masters
can lookup to serve cluster ID to clients. Active HMaster
is still responsible for creating it but all the masters
will read it from fs to serve clients.
RPCs exposing it will come in a separate patch as a part of
HBASE-18095.

* HBASE-23275: Track active master's address in ActiveMasterManager (#812)
Currently we just track whether an active master exists.
It helps to also track the address of the active master in
all the masters to help serve the client RPC requests to
know which master is active.

* HBASE-23281: Track meta region locations in masters (#830)
* HBASE-23281: Track meta region changes on masters
This patch adds a simple cache that tracks the meta region replica
locations. It keeps an eye on the region movements so that the
cached locations are not stale.
This information is used for servicing client RPCs for connections
that use master based registry (HBASE-18095). The RPC end points
will be added in a separate patch.

Includes the following, incorporating HBASE-20439 and HBASE-20440, too.
1)
HBASE-18133 Decrease quota reaction latency by HBase
Certain operations in HBase are known to directly affect
the utilization of tables on HDFS. When these actions
occur, we can circumvent the normal path and notify the
Master directly. This results in a much faster response to
changes in HDFS usage.
This requires FS scanning by the RS to be decoupled from
the reporting of sizes to the Master. An API inside each
RS is made so that any operation can hook into this call
in the face of other operations (e.g. compaction, flush,
bulk load).
2)
HBASE-18135 Implement mechanism for RegionServers to report file archival for space quotas
This de-couples the snapshot size calculation from the
SpaceQuotaObserverChore into another API which both the periodically
invoked Master chore and the Master service endpoint can invoke. This
allows for multiple sources of snapshot size to reported (from the
multiple sources we have in HBase).
When a file is archived, snapshot sizes can be more quickly realized and
the Master can still perform periodical computations of the total
snapshot size to account for any delayed/missing/lost file archival RPCs.
3)
HBASE-20531 RS may throw NPE when close meta regions in shutdown procedure.
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.

Break out the filesystem messing so don't have to copy it nor do more

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

Adds a "compaction_switch" to hbase shell. Switching off compactions will
interrupt any currently ongoing compactions. State set from shell will be
lost on restart. To persist the changes across region servers modify
hbase.regionserver.compaction.enabled in hbase-site.xml and restart.
