[FLINK-4177] Harden CassandraConnectorTest
This PR (hopefully) resolves the instability issues with the Cassandra
connector tests.
Changelog:
* updated cassandra/driver versions
* the `cassandra.yaml` was cleaned up
* removed several configuration values that used the default
* sorted the remaining settings in alphabetical order
* the at-least-once sinks were modified to
* properly log exceptions when close() is called
* keep track of how many records were not acknowledged yet
* the tests were modified to
* start the embedded cassandra instance in a separate process
* and supply an array of performance related jvm arguments, taken from
the cassandra repo
* no longer truncate tables; instead every test uses a separate table
* wait until a connection could be established to cassandra in a
retry-loop instead of waiting for a fixed time
* no longer run actual flink jobs
* use increased timeouts
* clean up temporary files
