upgrades:
  - mongodb.server.cluster no longer hardcodes the telemetry nodes' hostnames
    in favor of using `openstack_telemetry_node{01,02,03}_hostname` params,
    allowing custom hostnames to be used.

    Configuration example:

    .. code-block:: yaml

        parameters:
          _param:
            openstack_telemetry_node01_hostname: mdb01
            openstack_telemetry_node02_hostname: mdb02
            openstack_telemetry_node03_hostname: mdb03
