Adds an 'interfaces' endpoint in the API
(/nodes/{node}/lxc/{vmid}/interfaces'), which returns a list of
interface names, together with a MAC, IPv4 and IPv6 address. This list
may be expanded in the future. Note that this is only returned for
*running* containers, stopped containers simply return an empty list.
