    Added system metadata classes to deploy the InfluxDB relay service.

    The InfluxDB relay service replicates the InfluxDB data to a cluster of
    InfluxDB servers for HA.

    For more details about the service, see the `GitHub project
    <https://github.com/influxdata/influxdb-relay>`_ page.

    To enable it, add the ``system.influxdb.relay.cluster`` class to the
    Telemetry nodes and change
    ``system.haproxy.proxy.listen.stacklight.influxdb`` to
    ``system.haproxy.proxy.listen.stacklight.influxdb_relay``.
