Introducing Milvus Lite: the Lightweight Version of Milvus

Introduces Milvus Lite, a lightweight, self-contained, in-application Python library version of Milvus. It requires no external dependencies and can be integrated directly into Python applications, Colab, and Jupyter Notebooks for local development and experimentation. It is not recommended for production environments requiring high performance, availability, or scalability. Details installation via pip, usage as a Python module with `default_server.start()` and `connections.connect()`, CLI usage with `milvus-server`, debug mode, data/log persistence via `set_base_dir()` or `--data` flag, and configuration via Python APIs or CLI flags.
