To provide Application/environment isolation via weave subnets.

[enxebre]

As we are using weave proxy and not overriding the docker bridge now we should be able to provide a solution with granular subnet isolation per application/environment. http://docs.weave.works/weave/latest_release/features.html#application-isolation

Do we have a suggested approach on this or we need some investigation here ?
