Some testing improvements for Cassandra

* Remove the `cassandra.yaml` from test resources since it does not
have any effect on the clients.
Use `datastax-java-driver.basic.request.timeout` system property instead
with `10 seconds` value to allow Cassandra client to wait for query results
a little more than 2 seconds
* Expose just an IP address for contact endpoint avoiding overhead
with attempts to connect to all addresses returned by `localhost` resolution
* Bring back `log4j-slf4j-impl` dependency since it is required for other libs
