* Add a bit of javadoc around SerialReplicationChecker.
* Miniscule edit to the profiler jsp page and then a bit of doc on how to make it work that might help.
* Add some detail if NPE getting BitSetNode to help w/ debug.
* Change HbckChore to log region names instead of encoded names; helps doing diagnostics; can take region name and query in shell to find out all about the region according to hbase:meta.
* Add some fix-it help inline in the HBCK Report page – how to fix.
* 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
analysis.
* Reduces the warning count as reported by IntelliJ from 100 to 7.

- add CPU load
- fill the disk
- corrupt or delete regionserver data files

(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
