doc: point to relevant nova config in routed networks guide

Browse Source 
While the focus of the routed provider networks documentation
is on the Neutron side of things, this document provides a useful
location to point at relevant Nova configuration.

This reference relates to the Nova scheduler and ensuring that
instance move operations don't result in instances being scheduled
to hosts which do not have access to the required network(s).

#. Restart the ``neutron-server`` service.
#. (Optional) Configure the Nova scheduler to filter based upon routed network
host aggregates. Without this option set, once ports are attached to
instances and have IP addresses assigned, Nova may schedule instances to
hosts which do not have access to the required segment. See the `Nova
configuration reference
