REVISION SUMMARY
  Sharing a single config leads to undesired side-effects. The GetConfigOperation
  is assumed to always return a new copy of the current config that is not changed
  unless registered to ConfigMonitor. When sharing a single copy this assumption is
  broken which leads to misbehaviour in KDED.
  
  This change makes GetConfigOperation always return a new copy of the config that
  caller can register to ConfigMonitor if they want to, otherwise it remains
  unchanged until released.
