Subject: neutron.configure: Ensure /var/run is a symlink to /run

If /var/run is a directory that is not emptied every boot, then it will
contain references to stale network namespaces, which do not work when
neutron tries to create networks.

If it is flushed appropriately then neutron will create the namespaces
when it needs to.
