* feat: unblock LLM(stream=True) to work with tools
* feat: replace pytest-vcr by pytest-recording
1. pytest-vcr does not support httpx - which LiteLLM uses for streaming responses.
2. pytest-vcr is no longer maintained, last commit 6 years ago :fist::skin-tone-4:
3. pytest-recording supports modern request libraries (including httpx) and actively maintained
* refactor: remove @skip_streaming_in_ci
Since we have fixed streaming response issue we can remove this @skip_streaming_in_ci
