[tests] add client-sdk pytests & delete client.py (#638)

Browse source 
# 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
```
