API does not support limits parameter

[Heather Lemon]

The API only supports a list_all for networks.

        """Fetches a list of all networks for a project."""
        # Pass filters in "params" argument to do_request
        return self.list('networks', self.networks_path, retrieve_all,
                         **_params)

Needs additional function with acceptable limit params.
If I have 100 networks, all 100 networks are returned.
This affects both horizon and the cli.

openstack network list -f json --limit 1
