This patch reworks the Pod rolling mechanism, which is supposed to update Pods with each migration run, but since the it generates a new random value on each helm execution, this will constantly roll all pods in a GitOps driven deployment, which reconciles the helm release. This is resolved by fixing the upgrade to the `.Release.Revision`, which should stay identical, unless config or helm release version have been changed. Further it introduces automatic rolls based on adjustments to the environment variables and secrets. The implementation uses a helper template, following the 1-2-N rule, and omitting code duplication.
