ISPN-4389 Tests for suppressing state transfer with jmx fail

* Changed so cluster registry cache never has ST disabled
Updated readme file, failsafe plugin single test info
ISPN-4402 Add test for custom audit logger
ISPN-3530 ISPN-1855 Keep per-cache CH to route requests correctly

* It fixes an issue where accessing non-distributed caches can
break topology updates.
* Add asymmetric routing test that forces each server to hash
only to itself to replicate situations where different distributed
caches have different CH.
