KIJIMR-304. Cassandra tests in KijiMR should not use CMP

issue: https://jira.kiji.org/browse/KIJIMR-304

Just removed the integration tests for now because they will not work without
some kind of external Cassandra process.  Will enable them again with Bento
plugin.

Gets some more tests to pass.
Minor whitespace tidying.
All unit tests passing.

Issue was some keys not being populated in Configurations.
All unit tests pass. Testing integration tests now.
Pom tweaking for integration tests.
