Delete source system apartment using source system information

Operation is used to delete source system apartment using source system information.

Operation attempts to remove all references to the apartment and then proceed to delete it permanently. Deleted apartment cannot be restored.

Be aware, that in case of operation failing unexpectedly, some of the objects that were previously related to the apartment to be deleted may have already been re-mapped to default apartment despite of the original apartment still existing in the system as a result of failed operation. When operation fails, re-mapped objects will not be rolled back to their previous state.
