compute v2.1: os-attach-interfaces API is not documented

[Matt Riedemann]

The v2.1 os-attach-interfaces API is not documented in api-site:

https://github.com/openstack/nova/blob/12.0.0/nova/api/openstack/compute/attach_interfaces.py

http://developer.openstack.org/api-ref-compute-v2.1.html#os-attach-interfaces

However, the v2 API extension is documented:

http://developer.openstack.org/api-ref-compute-v2-ext.html#os-interface

We should document the same API in the v2.1 API docs.

We should also note that the API is only supported with neutron as the network backend since nova-network does not implemented the required network API:

    Document the os-attach-interfaces compute APIs in v2.1

    The documentation exists in the v2 extension page:
    http://developer.openstack.org/api-ref-compute-v2-ext.html#os-interface
    but not in the V2.1 docs:
    http://developer.openstack.org/api-ref-compute-v2.1.html
    It looks like the wadl file is there, but its not linked from the chapter.

    Closes-Bug: #1506545
