JMXCacheBuster resets the metrics state at various points in time. These
events can potentially race with a master shutdown. When the master is
tearing down, metrics initialization can touch a lot of unsafe state,
for example invalidated FS objects. To avoid this, this patch makes
the getMetrics() a no-op when the master is either stopped or in the
process of shutting down. Additionally, getClusterId() when the server
is shutting down is made a no-op.
Simulating a test for this is a bit tricky but with the patch I don't
locally see the long stacktraces from the jira.

* 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.

Certain operations in HBase are known to directly affect
the utilization of tables on HDFS. When these actions
occur, we can circumvent the normal path and notify the
Master directly. This results in a much faster response to
changes in HDFS usage.
This requires FS scanning by the RS to be decoupled from
the reporting of sizes to the Master. An API inside each
RS is made so that any operation can hook into this call
in the face of other operations (e.g. compaction, flush,
bulk load).

We don't do checkstyle as part of default "mvn install" since it takes significant
amount of time (~90sec) and slows builds and development. We only need it for pre-commits.
