Bug 7321: ELAN Pseudo-port flows not installed on new DPNs

 + Stateful info about the Elan for cloud-sc was being stored in
   CONFIG but it was trying to read it from OPERATIONAL

 + I took the chance of migrating it from AbstractDataChangeListener
   to AsyncDataTreeChangeListener since the former is deprecated. This
   change seems to fix the problem and now the listener is getting the
   DCNs
