[tests] add client-sdk pytests & delete client.py (#638)
# What does this PR do? **Why** - Clean up examples which we will not maintain; reduce the surface area to the minimal showcases **What** - Delete `client.py` in /apis/* - Move all scripts to unit tests - SDK sync in the future will just require running pytests **Side notes** - `bwrap` not available on Mac so code_interpreter will not work ## Test Plan ``` LLAMA_STACK_BASE_URL=http://localhost:5000 pytest -v ./tests/client-sdk ``` <img width="725" alt="image" src="https://github.com/user-attachments/assets/36bfe537-628d-43c3-8479-dcfcfe2e4035" /> ## Sources Please link relevant resources if necessary. ## Before submitting - [ ] This PR fixes a typo or improves the docs (you can dismiss the other checks if that's the case). - [ ] Ran pre-commit to handle lint / formatting issues. - [ ] Read the [contributor guideline](https://github.com/meta-llama/llama-stack/blob/main/CONTRIBUTING.md), Pull Request section? - [ ] Updated relevant documentation. - [ ] Wrote necessary unit or integration tests.
