feat: rocketmq add util func

[li-keli]

Describe what this PR does / why we need it

This pull request adds two new methods to the Producer struct in the RocketMQ package. The SendWithResult method allows sending messages with a custom tag and returns the send result. The SendMsg method is used for sending messages with a custom message format.

Does this pull request fix one issue?

NONE

Describe how you did it

I added two new methods to the Producer struct: SendWithResult and SendMsg. The SendWithResult method constructs a new message with a specified tag and sends it synchronously, returning the send result. The SendMsg method sends a custom message using the provided Message struct.

Describe how to verify it

To verify this change, you can follow these steps:

1. Use the SendWithResult method with a custom message and tag to send a message and verify that it returns the send result.
2. Use the SendMsg method with a custom Message struct to send a message and verify that it sends successfully.

Special notes for reviews

Please review the implementation of the SendWithResult and SendMsg methods for correctness and adherence to coding standards. Pay particular attention to error handling and logging in case of failures.
