Implement new WALEntrySinkFilter (as opposed to WALEntryFilter) and
specify the implmentation (with a no-param constructor) in config
using property hbase.replication.sink.walentrysinkfilter

Reenables the test. Adds facility to HBaseTestingUtility so
you can pass in ports a restarted cluster should use. This
is needed so retention of region placement, on which this
test depends, can come trigger (this is why it was broke
on AMv2 commit... region placement retention is done
different in AMv2).
Added new bulk assign createRoundRobinAssignProcedure to complement
the existing createAssignProcedure. The former asks the balancer for
target servers to set into the created AssignProcedures. The latter
sets no target server into AssignProcedure. When no target server
is specified, we make effort at assign-time at trying to deploy the
region to its old location if there was one.
The new round robin assign procedure creator does not do this. Use
the new round robin method on table create or reenabling offline
regions. Use the old assign in ServerCrashProcedure or in
EnableTable so there is a chance we retain locality.
Bulk preassigning passing all to-be-assigned to the balancer in one
go is good for ensuring good distribution especially when read
replicas in the mix.
The old assign was single-assign scoped so region replicas could
end up on the same server.

Cleanup around forceNewPlan. Was confusing.
Added a Comparator to sort AssignProcedures so meta and system tables
come ahead of user-space tables.

Remove the forceNewPlan argument on createAssignProcedure. Didn't make
sense given we were creating a new AssignProcedure; the arg had no
effect.
(createRoundRobinAssignProcedures) Recast to feed all regions to the balancer in
bulk and to sort the return so meta and system tables take precedence.
Miscellaneous fixes including keeping the Master around until all
RegionServers are down, documentation on how assignment retention
works, etc.
send assign meta region request to target server fail""
This is a revert of a revert; i.e a reapplication with the
log message fixed up and some added javadoc.
This reverts commit 9ef115163b.

- Deprecates old checkAnd*() operations in Table
- Adds Table#CheckAndMutateBuilder and implements it in HTable
Commiter note: When committing the patch, noticed redundant {@inheritDoc} being added in HTable.
Removed new and olds ones.

- Adds debug logging for future ease
- Removes 60s timeout since testRecoveryAndDoubleExecutionPreserveSplits is only halfway after a minute.
- Adds some comments
- Logging change: Some places report "regionState=" while others just "state=".
State machine procs also have "state=" in their logs. Let me change all region related logging to "regionState=" so that
1) it's consistent everywhere, 2) more filtered results when searching through logs.
Created a new WALKey Interface and a WALKeyImpl. The WALKey Interface
is surfaced to Coprocessors and throughout most of the code base.
WALKeyImpl is used internally by WAL and by Replication which need
access to WALKey setters.
Methods that were deprecated in WALObserver because they were exposing
Private audience Classes have been undeprecated now we have WALKey.
Moved over to use SequenceId#getSequenceId throughout. Changed
SequenceId#getSequenceId removing the IOE.
