Start to clear out things that come from the CassandraResource and
fixed an issue with logging where always the abstract base class'
logger seems to be used instead of the tests.

This reverts commit 3bab67de9f60c704f9687546be8cb746f6c73219.
Reduced the complexity of the module test mechanism:

  o Removed the RestRunner and it's Context annotation
  o Removed the RestContextTest
  o Added a TestRule implementation that extends TestContext
  o Falling back to using the CassandraRunner which allows
    us to use the simple mechanisms as before to replace it
    with the CassandraResource
