…ations (#2275)

Add checksum for CMP ConfigMap in repo-server

This helm chart defines the plugins as ConfigMaps -- according to the docs, when the CM is modified, the repo-server Pod must be restarted to have the sidecars pick up the latest changes:

https://argo-cd.readthedocs.io/en/stable/operator-manual/config-management-plugins/#debugging-a-cmp

The changes in this helm chart allow for a checksum to be calculated from the ConfigMap and added as a Pod annotation so whenever the CM values are modified, the Pod is restarted automatically.
