[cassandra] deploy the replaying stack
In order to ingest data in cassandra, we need a replayer stack
The simpler is probably to deploy the storage/replayer service in kubernetes as during the test on grid5000
For the record, the configuration used for the grid5000 deployment is here: https://forge.softwareheritage.org/source/snippets/browse/master/sysadmin/grid5000/cassandra/kubernetes/
