2.12 - Exposes VIF net-id attribute in os-virtual-interfaces. User will be
able to get Virtual Interfaces net-id in Virtual Interfaces list and can
determine in which network a Virtual Interface is plugged into.
novaclient.base.Resource class is a parent class of VirtualInterface resource.
Since `Resource` is a universal interface for any resources and doesn't
require hard-code attributes which describe partial resource, there are no
required changes to support this microversion in "novaclient as a lib".
"novaclient as CLI" doesn't provide an interface for VirtualInterface yet
(see bug 1522424 for more details). When it will be implemented, we will need
to check that new attribute is displayed correctly.
Based on the fact that 1522424 is not resolved and novaclient.base.Resource
class has enough tests, this patch doesn't require any tests.
Also this patch fixes representation of VirtualInterface resource.
