Add Tenancy Support to VLAN Group

Proposed functionality

Add the tenant field to the VLANGroup model to support tenancy. Ideally, show the tenant with an "*" appended in the Tenant column on the VLAN table for a VLAN that is not explicitly assigned to a Tenant, but inherited from its group, just like is done with the IPAddress table when its Prefix has an assigned Tenant.

Use case

The VLAN model already supports tenancy, so it's curious why the VLANGroup model does not. When using a VLANGroup to document the VLANs on an ENNI, it would be useful to also associate the group to a Tenant and not just the VLAN members under it. This would also allow for additional validation opportunities, like it could be enforced that the Tenant set on the VLAN and VLANGroup match (I think it makes sense to leave this as a custom validation opportunity). We added a custom field for this in our environment today, but that has the limitation that when you go to the details page for a Tenant, it is not listed under the related objects.

Database changes

Add nullable tenant ForeignKey to tenancy.Tenant.
