Operator is missing permissions for `Leases` resources

[jneuff]

Installing your helm chart as is, results in the operator being unable to create its Leases, because it is missing the permissions to do so. Shouldn't this be part of the /templates/role.yaml? E.g.:

..
- apiGroups:
  - "coordination.k8s.io"
  resources:
    - leases
  verbs:
  - get
  - update
  - patch
  - create

I am not sure which verbs it needs, definitely create.
