All the clients need to know the master RPC end points while using master
based registry for creating cluster connections. This patch amends the
test cluster utility to populate these configs in the base configuration
object used to spin up the cluster.
The config key added here ("hbase.master.addrs") is used in the subsequent
patches for HBASE-18095.

* Add counts in procedures page so can see if making progress; move listing of WALs to end of the page.
Have the existing scheduleRecoveries launch a new HBCKSCP
instead of SCP. It gets regions to recover from Master
in-memory context AND from a scan of hbase:meta. This
new HBCKSCP is For processing 'Unknown Servers', servers that
are 'dead' and purged but still have references in
hbase:meta. Rare occurance but needs tooling to address.
Later have catalogjanitor take care of these deviations
between Master in-memory and hbase:meta content (usually
because of overdriven cluster with failed RPCs to hbase:meta,
etc)
Changed expireServers in ServerManager so could pass in
custom reaction to expired server.... This is how we
run our custom HBCKSCP while keeping all other aspects
of expiring services (rather than try replicate it
externally).
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.

* Clean up a bunch of private variable leakage into other
classes. Reduces visibility as much as possible, providing getters
where access remains necessary or making use of getters that
already exist. There remains an insidious relationship between
`HRegionServer` and `RSRpcServices`.
* Rename `fs` to `dataFs`, `rootDir` as `dataRootDir` so as to
distinguish from the new `walFs`, `walRootDir` (and make it easier
to spot bugs).
* Cleanup or delete a bunch of lack-luster javadoc comments.
* Delete a handful of methods that are unused according to static

(cherry picked from commit 577db5d7e5 - Test only, removed changes from no more exisiting ScannerCallableWithReplicas class)
Removes the closeRegion flag added by HBASE-23181 and instead
relies on reading meta WALEdit content. Modified how qualifier is
written when the meta WALEdit is for a RegionEventDescriptor
so the 'type' is added to the qualifer so can figure type
w/o having to deserialize protobuf value content: e.g.
HBASE::REGION_EVENT::REGION_CLOSE
Added doc on WALEdit and tried to formalize the 'meta' WALEdit
type and how it works. Needs complete redo in part as suggested
by HBASE-8457. Meantime, some doc and cleanup.
Also changed the LogRoller constructor to remove redundant param.
Because of constructor change, need to change also

Make it so hbase:meta can be altered. TableState for hbase:meta
is kept in Master. State is in-memory transient so if Master
fails, hbase:meta is ENABLED again. hbase:meta schema will be
bootstrapped from the filesystem. Changes to filesystem schema
are atomic so we should be ok if Master fails mid-edit (TBD)
Undoes a bunch of guards that prevented our being able to edit
hbase:meta. At minimmum, need to add in a bunch of WARNING.

Space quotas has a feature which intends to avoid enacting a space quota
violation policy when only a subset of the Regions for that Table have
reported their space usage (under the assumption that we cannot make an
informed decision if we do not include all regions in our calculations).
This had the unintended side-effect, when a table is disabled as a part
of a violation policy, of causing the regions for that table to not be
reported which disables the violation policy and enables the table.
Need to make sure that when a table is disabled because of a violation
policy that the code does not automatically move that table out of
violation because region sizes are not being reported (because those
regions are not open).

There was a bug in which we would not drop the RegionSizes
for a table in a namespace, where the namespace had a quota
on it. This allowed a scenario in which recreation of a table
inside of a namespace would unintentionally move into violation
despite the table being empty. Need to make sure the RegionSizes
are dropped on table deletion if there is _any_ quota applying
to that table.

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.

currently.
