Implemented SR transaction rollbacking during configuration changes.

Browse Source 
SR tranasctions are BF aborted or rolled back on primary view
changes according to the following rules:
* Ongoing local SR transactions are BF aborted if the processing
  server is not found from the current view.
* All remote SR transactions whose origin server is not included in the
  current view are rolled back.
