feat(cloudnative-pg): add annotations to all CRDs

We want to be able to pass annotations to all CustomResourceDefinitions.

This is helpful in that it allows passing an annotation to ArgoCD to
enable ServerSideApply:

```
crds:
  annotations:
    argocd.argoproj.io/sync-options: ServerSideApply=true
```

Fixes #656
