Introduce crds directory for compatibility with Helm v3 (#738)
* Introduce crds directory for compatibility with Helm v3 This commit introduce a crd directory for the helm chart which has all custom resource definitions. The files in the crd directory is plain YAML. The crds got the label `app.kubernetes.io/name: postgres-operator` and removes all the templating. Helm v3 ignores the objects from the `templates` directory which have a `crd-install` hook. This commit addes templates/crds.yaml which generates YAMLs for CRDs. The hooks from these CRDs are detected by Helm v2 as well as v3. Helm v2 executes the hook and Helm v3 ignores the hook (YAML files are not applied) The approach is inspired by the prometheus-operator chart helm/charts@89b233eef6
