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).

* 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
