    Inherit segmentation details for trunk subports if requested

    This patch introduces support for requests where the user does
    not know the segmentation details of a subport and by specifying
    segmentation_type=inherit will let the trunk plugin infer these
    details from the network to which the subport is connected to, thus
    ignoring the segmentation_id in case it were to be specified.

    This type of request is currently expected to have correct results
    when the network segmentation type is 'vlan', and the network has
    only one segment (provider-net extension use case).

    DocImpact: Extend trunk documentation to include Ironic use case.
