[jira] [HBASE-5684] Make ProcessBasedLocalHBaseCluster run HDFS and make it more
robust

Summary:
Currently ProcessBasedLocalHBaseCluster runs on top of raw local filesystem. We
need it to start a process-based HDFS cluster as well. We also need to make the
whole thing more stable so we can use it in unit tests.

Also all logs of local HBase cluster daemons are now tailed to the primary log
of the unit test with the appropriate prefixes to make debugging easier.

This is a trunk diff. The 89-fb version is D2709.

Test Plan:
Run the new unit test multiple times (10x or 50x).
Run all unit tests.
