This patch switches to the builder pattern by adding a helper method.
It also checks to ensure that the pattern is available (i.e. that
HBase is running on a hadoop version that supports it).

A reattempt at fixing HBASE-20173 [AMv2] DisableTableProcedure concurrent to ServerCrashProcedure can deadlock
The scenario is a SCP after processing WALs, goes to assign regions that
were on the crashed server but a concurrent Procedure gets in there
first and tries to unassign a region that was on the crashed server
(could be part of a move procedure or a disable table, etc.). The
unassign happens to run AFTER SCP has released all RPCs that
were going against the crashed server. The unassign fails because the
server is crashed. The unassign used to suspend itself only it would
never be woken up because the server it was going against had already
been processed. Worse, the SCP could not make progress because the
unassign was suspended with the lock on a region that it wanted to
assign held making it so it could make no progress.
In here, we add to the unassign recognition of the state where it is
running post SCP cleanup of RPCs. If present, unassign moves to finish
instead of suspending itself.
Includes a nice unit test made by Duo Zhang that reproduces nicely the
hung scenario.

Change addOperationToNode so we throw exceptions that give more detail

Have expireServer return true if it actually queued an expiration. Used

Hide methods that shouldn't be public. Add a particular check used out

Check that server we're to move from is actually online (might
catch a few silly move requests early).

Add doc on ServerState. Wasn't being used really. Now we actually stamp
a Server OFFLINE after its WAL has been split. Means its safe to assign
since all WALs have been processed. Add methods to update SPLITTING
and to set it to OFFLINE after splitting done.

Change logging to be new-style and less repetitive of info.
Cater to new way in which .addOperationToNode returns info (exceptions
rather than true/false).
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java
Add looking for the case where we failed assign AND we should not
suspend because we will never be woken up because SCP is beyond
doing this for all stuck RPCs.
Some cleanup of the failure processing grouping where we can proceed.
TODOs have been handled in this refactor including the TODO that
wonders if it possible that there are concurrent fails coming in
(Yes).

Doc and removing the old HBASE-20173 'fix'.
Also updating ServerStateNode post WAL splitting so it gets marked

Add a counter for 'attempts' used when 'stuck' to implement backoff.
Add suspend with timeout when 'stuck'. Add callback when timeout is

Changes for HBASE-20027 seem to cause UI not showing up on default port in standalone mode. For concurrent
unit test execution, individual tests can set hbase.localcluster.assign.random.ports to true or modify

Log less. Log using same format as used elsewhere in log.
Align logs in HFileArchiver with how we format elsewhere. Removed
redundant 'region' qualifiers, tried to tighten up the emissions so
easier to read the long lines.

Make the emissions in here trace-level. When more than a few regions,
log is filled with this stuff.
We assumed that we can run for loop from 0 to lastStep sequentially. MergeTableRegionProcedure skips step 2. So, when i is 0 the procedure is already at step 3.
Added a method StateMachineProcedure#getCurrentStateId that can be used from test code only.
* rely on git plumbing commands when checking if we've built the site for a particular commit already
* switch to forcing '-e' for bash
* add command line switches for: path to hbase, working directory, and publishing
* only export JAVA/MAVEN HOME if they aren't already set.
* add some docs about assumptions
* Update javadoc plugin to consistently be version 3.0.0
* avoid duplicative site invocations on reactor modules
* update use of cp command so it works both on linux and mac
* manually skip enforcer plugin during build
* still doing install of all jars due to MJAVADOC-490, but then skip rebuilding during aggregate reports.
* avoid the pager on git-diff by teeing to a log file, which also helps later reviewing in the case of big changesets.

Fix MoveRandomRegionOfTableAction. It depended on old AM behavior.
Make it do explicit move as is required in AMv3; w/o it, it was just
closing region causing test to fail.
Fix pom so hadoop3 profile specifies a different netty3 version.
Bunch of logging format change that came of trying trying to read
the spew from this test.
Rename the PE Worker threads.
Send an interrupt if worker taking a long time to go down
(it may be RPC'ing out to a dead server, retrying so
interrupt). Also join on the ProcedureExecutor shutting down.
This will make problems shutting down more obvious.
Disable TestRegionsOnMasterOptions. Master carrying Regions is broke.
Set the ProcedureExcecutor worker threads as daemon.
Ditto for the timeout thread.
Remove hack from TestRegionsOnMasterOptions that was
put in place because the test would not go down.
