[Investigation] Fully-native Python client

I'm rather new to this project but, I thought it might be worthwhile to gauge the community's thoughts on implementing a fully-native Python client. Those of you who have a more intimate understanding of the internals, my questions would be:

- Is it feasible that a native Python client be developed, or are there any potential show-stopping limitations (i.e., the C++ client can handle some task that Python isn't well-suited for)
- Given that it is feasible, is the investment of effort worthwhile? Or is wrapping functionality from the C++ client a better approach at least in the short-medium term?
- Any other thoughts along these lines?

Also, if there is a better venue for starting this conversation (i.e., the main pulsar repo, the C++ client repo, or the dev mailing list) let me know and i'll close this and start it there. I just had the thought that maybe those who have worked with the Python client specifically might have a clearer understanding of the pros and cons of going in that direction.

首先檢視 Python 用戶端和 C++ 用戶端，以了解它們各自的內部實作和能力。比較 Python 是否能夠在不封裝 C++ 的情況下支援所需功能，然後記錄可行性、限制以及為社群建議的方向。
