REST API should allow router filtering by network_id

[John Schwarz]

There is currently no way to display all routers that are connected to a certain network. This makes it hard for large deployments to figure out which networks are connected to which routers. The proposed change adds this functionality to the REST API, which should also give the end-user the ability to apply this filter using the neutronclient.

Per my own confusion, moving back to Juno-RC1.

[Kyle Mestery (mestery)]

Remove Juno-RC1 milestone.

This should really be filed as a spec since this is a change to the API.

Reason: Since changes to the query_model_hook system is not something we want to do, this changeset is irrelevant.
