Fix seed VM configdrive when admin network is a VLAN

The jriguera.configdrive role does not add VLAN=yes to the ifcfg script
of a VLAN interface on the seed VM, unless type=vlan is passed in the
network device list. This change passes this field for VLAN interfaces.

Depends on https://github.com/jriguera/ansible-role-configdrive/pull/11
