optimize srv broker and executor logic (#630)

### What problem does this PR solve?

Optimize task broker and executor for reduce memory usage and deployment
complexity.

### Type of change
- [x] Performance Improvement
- [x] Refactoring

### Change Log
- Enhance redis utils for message queue(use stream)
- Modify task broker logic via message queue (1.get parse event from
message queue 2.use ThreadPoolExecutor async executor )
- Modify the table column name of document and task (process_duation ->
process_duration maybe just a spelling mistake)
- Reformat some code style(just what i see)
- Add requirement_dev.txt for developer
- Add redis container on docker compose
