Integration test script should test the Python bindings

**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**

**Additional context**

Start by locating the integration test script and its existing benchmark invocation for the scheduler, executor, and Rust client. Update the test path to run the benchmarks through Python, then verify that the integration run exercises the Python bindings and completes successfully.
