      If a command returns a NoSuchTransaction error and there was a write concern provided on the command, perform a noop write before waiting for write concern. This ensures that if the command was run with write concern w:majority, and the write concern succeeds, then it is safe to attach the TransientTransactionError label. That is, it is safe for the driver/application to retry the entire transaction, since the node is primary, so the transaction cannot have committed on a newer primary.

      Since secondaries reject all commands with write concern, we will not attempt to perform the noop write on secondaries.

      This ticket must resolve all TODOs for SERVER-38132 and SERVER-38133, since it replaces those two tickets.
