It seems the DB username and password are not configurable #142

I am trying to deploy Tranquil PDS on my k8s cluster, but I cannot see any way to configure the DB credentials, which seems like an oversight since the default password is just postgres. I would like this as I am using CNPG which outputs the creds into a k8s secret which can later be referenced in the deployment.yaml to pull env var values from.

CNPG docs: https://cloudnative-pg.io/docs/1.30/applications/

Did I miss the config values or is this not yet implemented?

Thanks a lot ^^
