Description

There were bugs in the Azure setup as the new TF provider no longer allowed for the old setup. Secondly the k8s template was wrong. Now both have been fixed in this PR.

Note: we do see that the current resource defs on TF are very tight for this setup. it works, but you cannot deploy anything next to the testing setup.
