Replaced CLI with CQL in this test

Removing CLI from this test was pretty easy and I have had it done for a while.  Wanting to just get this merged.  I have two other tests that need to be converted for CASSANDRA-5586.  I got a little stuck on one of those tests and I am going to switch gears for the moment.  More work will be done on this branch in the near future, but would like to get this checked in.
