ACCUMULO-2227 / ACCUMULO-2228 Update randomwalk README with HA warning

Hadoop 2.1.0 includes better retry / failover handling than prior versions. This
commit adds a warning to the randomwalk README advising testers to expect more
failures exercising HA under Hadoop versions before 2.1.0.

+If you are running randomwalk tests while exercising Hadoop's high availability
+(HA) failover capabilities, you should use Hadoop version 2.1.0 or later.
+Failover scenarios are more likely to cause randomwalk test failures under
