- Increment retries: waiting 20 seconds (i.e., 10 retries) seem to
  be not enough for monasca-grafana to start on the first node.
  Increasing to 80 seconds (i.e., 40 retries) fixes the issue.

- Prevent the check from running when kolla_action=config. In that
  case, the command would never succeed as the service is not
  deployed yet (similarly to
  https://review.opendev.org/c/openstack/kolla-ansible/+/771237).
