      Executes the transactional batch.

      Parameters: cosmosBatch - Batch having list of operation and partition key which will be executed by this container. Returns: A TransactionalBatchResponse which contains details of execution of the transactional batch.

      If the transactional batch executes successfully, the value returned by CosmosBatchResponse.getStatusCode() on the response returned will be set to 200}.

      If an operation within the transactional batch fails during execution, no changes from the batch will be committed and the status of the failing operation is made available by CosmosBatchResponse.getStatusCode() or by the exception. To obtain information about the operations that failed in case of some user error like conflict, not found etc, the response can be enumerated. This returns CosmosBatchOperationResult instances corresponding to each operation in the transactional batch in the order they were added to the transactional batch. For a result corresponding to an operation within the transactional batch, use CosmosBatchOperationResult.getStatusCode() to access the status of the operation. If the operation was not executed or it was aborted due to the failure of another operation within the transactional batch, the value of this field will be 424; for the operation that caused the batch to abort, the value of this field will indicate the cause of failure.

      If there are issues such as request timeouts, Gone, session not available, network failure or if the service somehow returns 5xx then this will throw an exception instead of returning a CosmosBatchResponse.

      Use CosmosBatchResponse.isSuccessStatusCode() on the response returned to ensure that the transactional batch succeeded.
