Proposed functionality

Copy the qinq_role field from the Vlan model to the VlanGroup model. Add validation to only allow VLANs of the same role in the group.

If the Q-in-Q role is empty, I think it makes sense to allow VLANs with any Q-in-Q role, but I could also see an argument to only allow VLANs without a Q-in-Q role set and to add an additional Q-in-Q role of "Any" or "Mixed" to the VLAN Group model to explicitly allow VLANs with non-empty Q-in-Q roles as well.

Use case

If using a VLAN Group to document the VLANs available on an ENNI, they must all be SVLANs, likewise on a UNI they must all be CVLANs, so it would be nice to have the system be able to enforce that out of the box.

Database changes

Copy the qinq_role field from the Vlan model to the VlanGroup model.
