Description

Currently ChaosMonkeyRunner performs looping unconditionally:

    while (true) {// loop here until got killed
      Thread.sleep(10000);
    }

When ChaosMonkeyRunner is invoked programmatically, it is desirable to add interruptibility to the runner so that the caller can manage its lifetime.

Another enhancement is to allow passing the path to hbase-site.xml where chaos monkey parameters are specified.
This is useful when the underlying hbase-site.xml is not on classpath.
