Avoid unnecessary pod restart on each helm chart version

[jkroepke]

This PR changes the the input of the config checksum which triggers the reload.

On main branch, the whole configmap/secret checksum is included as checksum input. The configmap contains labels which includes the helm chart version. Each new helm chart version forces a pod restart which is not always necessary.

By define a finer input for the pod annotation checksum, unnecessary pod restarts can be avoided.

The PR implements this for

• config
• alpha config
• secrets
• htpasswd

and could be extended to

• redis
• email
• google secret
