### Motivation and Context
Python integration tests were failing consistently for 2 reasons. First,
all ubuntu system tests were failing due to missing shared object files
related to cuda. Second, macOS + python 3.11 tests were failing due to
hsnwlib unable to install on native hardware.
See https://github.com/microsoft/semantic-kernel/pull/1066 for
description of changes to integration test code to condense test code,
make better use of pytest fixtures, and reduce the number of calls to
external APIs (OpenAI, AOAI)
### Description
- Integration tests were failing on Linux due to a regression in python
torch=2.0.1. Downgrading the version to 2.0.0 resolved these failures.
- For MacOS + 3.11 specifically, setting the environment variable
`HNSWLIB_NO_NATIVE=1` ensures that the hnswlib wheel can be built and
installed properly on M1 hardware.
- Python integration tests reliably and consistently passing:
