Implement DELETE EthernetInterface for VLAN

After using EthernetInterface to represent a VLAN interface, DELETE
handler is required for deleting VLAN interfaces.

Tested:
* VLAN interfaces can be deleted successfully via DELETE request.
* Deleting a physical interface returns ResourceCannotBeDeleted error.
* Deleting a non-existent interface returns ResourceNotFound error.
