Requirements: Is tls useful/required for glvd-postgres?

[fwilhe]

The default image of glvd-postgres sets up tls which increases the complexity of the setup. Considering that we don't want to expose the database, this would only encrypt cluster-internal traffic. I'm not sure if we really need this.

The original design of glvd assume the db is exposed for the ingestion process, but we don't need that. The design is to run the ingestion process inside the cluster so the db does not need to accept any connections from outside the cluster.

removed for now, leaving this issue open for discussion on the requirement. Close once we agreed.
