[FLINK-25147][connectors][test] Migrate Cassandra connector tests to testContainers backport to release 1.13

[echauchot]

This PR is the backport of this merged PR to release 1.13.

For DockerImageVersions it was not present in release 1.13 so I inlined in the test:
private static final String CASSANDRA_3 = "cassandra:3.0";
