refactor(tests): delete inference, safety and agents tests from providers/tests/ (#1393)

Browse source 
Continues the refactor of tests. 

Tests from `providers/tests` should be considered deprecated. For this
PR, I deleted most of the tests in
 - inference
 - safety
 - agents
since much more comprehensive tests exist in
`tests/integration/{inference,safety,agents}` already.

I moved `test_persistence.py` from agents, but disabled all the tests
since that test needs to be properly migrated.

## Test Plan

```
LLAMA_STACK_CONFIG=fireworks pytest -s -v agents --vision-inference-model=''
/Users/ashwin/homebrew/Caskroom/miniconda/base/envs/toolchain/lib/python3.10/site-packages/pytest_asyncio/plugin.py:208: PytestDeprecationWarning: The configuration option "asyncio_default_fixture_loop_scope" is unset.
The event loop scope for asynchronous fixtures will default to the fixture caching scope. Future versions of pytest-asyncio will default the loop scope for asynchronous fixtures to function scope. Set the default fixture loop scope explicitly in order to avoid unexpected behavior in the future. Valid fixture loop scopes are: "function", "class", "module", "package", "session"
