Patch: Add a new ipynb example and add the corresponding patch to the python_v2 kernel.

[birdflyi]

Purpose

• Attempting to fix #961
• Connect the data access layer (to clickhouse and neo4j), query method layer and the query call layer for jupyter notebook ipynb files.
• Add a patch python_v2 kernel(a version 2 of python3 environment), Optimizing redundant code and unnecessary nested classes and functions using Python's features.

Features and Current Progress

• The python kernel is able to be called compatibly with py files and ipynb files outside the packages root directory.
• The index.py in pyhton_v2 is synchronized many function interfaces with index.ts in node kernel, which can be implement separately.
• A function getRepoOpenrank() has been implemented and tested with the aliyun clickhouse service of X-lab, which offered a template way to connect data and function callers.

Threats

• The ipynb file is another implementation method for last year's annual report, however, the new year is around the corner.
• Many function interfaces need to be implemented.
• There are too many redundant versions, such as python kernel and python_v2, different implementation methods for the same functions(some function was kept in comments)...
• Different language characteristics, and performance optimizations: the asyn/await feature is still waiting to be added.
