Armando Migliaccio 4a6d06550b 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.

features:
- Subport segmentation details can now accept ``inherit`` as segmentation
type during a trunk creation/update request. The trunk plugin will
determine the segmentation type and ID and replace them with those of
the network to which the port is connected. Only single-segment VLAN
networks are set to have expected and correct results at this point.
