Integration test script should test the Python bindings

[andygrove]

Is your feature request related to a problem or challenge? Please describe what you are trying to do. The integration test script tests the scheduler, executor, and Rust client, but not the Python bindings.

Describe the solution you'd like Run the benchmarks using Python instead of Rust. This will test both the Python bindings and the Rust client.

Describe alternatives you've considered
