docs: Set the status of an executed transaction.
  
          Called by the executor after a transaction has been processed.
  
          The scheduler must know when transactions have finished being
          applied so that it can determine which transactions will become
          eligible for processing.
  
          Args:
              txn_signature (str): The signature of the transaction, which
                  must match the header_signature field of the Transaction
                  object which was part of the added Batch.
              is_valid (bool): True if transaction applied successfully or False
                  if the transaction failed and was not applied.
              context_id (str): If status is True, contains the context_id
                  associated with the state changes made by the transaction.
                  If status is False, this should be set to None.
  
          Raises:
              ValueError: Thrown if transaction_signature does not match a
              transaction.
