[Nate Sias]

Filed on behalf of client.

Requesting ability to hide router / floating ip information in the Horizon Dashboard through a Juju configuration item.

This requires a configuration item which will set "'enable_router: false'" in /etc/openstack-dashboard/local_settings.py under heading OPENSTACK_NEUTRON_NETWORK.

    in the horizon. To hide the router/floatin-ip panel, set the config
    option 'enable-router-panel=False'. Default value is True.
