ifconfig: T2653: convert VLAN interfaces do discrete class

Instead of using an Adapter pattern to make interfaces VLAN-aware, create a
derived class named VLANIf to represent a VLAN. This change was necessary to
eliminate mixed code in Interfaces class which was VLAN - free, but recently
gained some VLAN specific code for set_admin_state().

In addition this "autoresolves" the issue in T2894 as a bond vlan interface
will no longer change the lower interface.
