[OVN] HW offload event "QoSMinimumBandwidthEvent" fails if the min-bw rule is removed

[Rodolfo Alonso]

When the logical switch port "qos_min_rate" option is removed (for example when the QoS policy is unset from the port), the LSP.options dictionary doesn't have the "qos_min_rate". That leads to the following error: https://paste.opendev.org/show/be29CRKNP03adrTUZ0WH/

    [OVN] Use the BW values retrieved from ``get_port_qos``

    In ``QoSMinimumBandwidthEvent`` and ``QoSBandwidthLimitEvent``, the
    bandwidth value is provided by the method ``get_port_qos``. This method
    handles when the value to be retrieved is not present in the
    required register and returns 0.
