Fixes for contrail-status:
1. Report 'STARTING' from supervisorctl as 'initializing' in
   contrail-status
2. Try to extract node UVE only from daemons implementing it.
   If we do not get node UVE from these daemons report state as
   'initializing'. The above changes will make sure that the
   contrail-status reported state will move to 'active' only
   after the process has initialized properly.
