…est that restart the cluster

Summary:
Keeping the `CassandraSession` object live during the yb cluster restart in these tests exposes a data race in the cassandra-cpp-driver library. This diff drops the connection before doing the restart to avoid the race.

Close the cassandra client before restarting the yb cluster. Having an open cassandra client when restarting a yb cluster exposes a data race in the yb cassandra driver. Follow up to D18376.
