This commit will allow for the following tests to run against C* 1.2.x:
async, basics, by_name, collections, outage, paging, stress, and
version1. The basics test suite was also enhanced to perform simple
statement queries for all data types. Tests that also are not applicable
to a particular C* instance can now be skipped without starting up a
cluster (e.g. basics and serial consistency tests are skipped on C* 1.2.x).

Minor cleanup along with a memory leak was also addressed.
