[Improve] Optimization of TubeMQ SDK usage demo

[gosonzhang]

Description

The example under the directory [1] is not from the user's perspective，and not friendly:

1. There is meaningless class encapsulation, which can actually be written more directly;
2. The implementation logic is not clear enough, the general processing needs to be extracted to facilitate the clear display of the main content of the Demo
3. No detailed notes

I want to improve this area so that users can use it better.
