Portal uses currently a customized, old Cassandra Image (cassandra_music:3.0.0).
This image doesn`t support IPv4/IPv6 dual-stack, and we are not legally permitted to use such a cassandra image. Thus we need to migrate to a publicly available image.

Initila tests has shown this image:

docker.io/library/cassandra:3.11.9 ... works properly, although, there might be some additional issues to be solved in a configuration of that image, or pre-configuration needed for Portal.

This will most probably be done with an init container starting before core portal-fe/be pods.

This needs to be address in this Jira Story, as part of REQ-432 (Dual stack IPv4/IPv6 support)
