Helm CI on file and postgres only

Looks like now that the CI runs with helm it only runs on local postgres and file based objectstore.

This is the case for all runners meaning that Oracle DB is ignored as well as Ceph objectstore.

Implemented Solution

For now the Values.yaml contain a structure for the credentials that need to be provided, to inject the real credentials.

Future work

We could rework this such that, the credentials are injected into the k8s cluster and the template uses the lookup feature to fetch them and the only thing we need to specify is the name of the resources we want to use.
