          Description

          If the read is successful (returns no error otherwise and all locks are released), we then:

          Generate noop writes that should be replicated to a majority of secondary nodes. When awaitReplication returns, then the primary will know it is the true primary of the set.

              Linearizable Reads require writes with write concern majority.
              If an error occurs: error statuses are passed back up without uasserts/invariants. If the noop write fails to replicate, the write concern error status returned from awaitReplicaton is turned into a LinearizableReadConcernError status with status code: 187.
