      Currently, we update the stable timestamp inside ReplicationCoordinatorImpl::_setStableTimestampForStorage by computing the stable optime from the set of stable optime candidates. We should remove the dependence on the stable optime candidates for setting the stable timestamp and updating the committed snapshot when enableMajorityReadConcern:true. We should be able to set the stable timestamp for storage directly as min(all_durable, lastCommittedOpTime). We will not remove any of the logic for computing and updating the stable optime candidates set as a part of this ticket.
