Remove unused methods from Sleeper (its ok, its @Private).
Remove notion of startTime from Sleeper handling (it is is unused).
Allow passing in how long to sleep so can maintain externally.
In HRS, use a RetryCounter to calculate backoff sleep time for when
reportForDuty is failing against a struggling Master.
Add a check for hbase:meta being online before we go to read it.
If not online, move into a holding-pattern until rectified, probably
by external operator.
Incorporates bulk of patch made by Allan Yang over on HBASE-21035.
M hbase-common/src/main/java/org/apache/hadoop/hbase/util/RetryCounterFactory.java
Add a Constructor for case where retries are for ever.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
Move stuff around so that the first hbase:meta read is the AM#loadMeta.
Previously, checking table state and/or favored nodes could end up
trying to read a meta that was not onlined holding up master startup.
Do similar for the namespace table. Adds new methods isMeta and
isNamespace which check that the regions/tables are online.. if not,
we wait logging with a back-off that assigns need to be run.

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).

Add switching on/off of compactions.
Switching off compactions will also interrupt any currently ongoing compactions.
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.

* modify the jar checking script to take args; make hadoop stuff optional
* separate out checking the artifacts that have hadoop vs those that don't.
* * Unfortunately means we need two modules for checking things
* * put in a safety check that the support script for checking jar contents is maintained in both modules
* * have to carve out an exception for o.a.hadoop.metrics2. :(
* fix duplicated class warning
* clean up dependencies in hbase-server and some modules that depend on it.
* allow Hadoop to have its own htrace where it needs it
* add a precommit check to make sure we're not using old htrace imports
