HBASE-25867 Extra doc around ITBLL (#3242) 

* HBASE-25867 Extra doc around ITBLL

Minor edits to a few log messages.
Explain how the '-c' option works when passed to ChaosMonkeyRunner.
Some added notes on ITBLL.
Fix whacky 'R' and 'Not r' thing in Master (shows when you run ITBLL).
In HRS, report hostname and port when it checks in (was debugging issue
where Master and HRS had different notions of its hostname).
Spare a dirty FNFException on startup if base dir not yet in place.

* Address Review by Sean
