This patch adds two services, one for web, which can be exposed by an
ingress, and one of type LoadBalancer that is exposed directly, to cut
down on transfer overhead using a relay or alike.

This patch migrates the previously separately managed helm chart into
this monorepo in order to profit from the already existing, unified
setup for chart and repository updates, as well as making sure, that
things keep being maintained.

Rook didn't fly properly and currently causes some issues with cluster usage,
therefore dropping it, should help to reduce load on the cluster.

This patch updates K8s to 1.23.16
