[refactor]Add Data Center Information Query and Log Data Pre- and Post-Processing

This PR aims to enhance the application environment information query function by introducing data center information to improve the traceability and management efficiency of log data. Additionally, pre- and post-processing logic is added to log-stream to ensure the completeness and accuracy of log data.

Changes:

1.Data Center Information Query: Add data center information fields to the application environment information query interface for tracking the source of log data.
2.Log Data Pre- and Post-Processing: Implement pre- and post-processing logic for log data in the log-stream module, including but not limited to data cleaning, formatting, encryption, etc.
Related Code Changes:

Add data center information fields to the application environment information query interface.
Implement pre- and post-processing logic for log data in the log-stream module.

Start by locating the application environment information query interface and the log-stream module. Review how environment fields and log data currently flow before defining the needed changes. Done means the interface exposes data center information and log-stream applies the agreed pre- and post-processing while preserving complete, accurate log data.
