Verify tests are fully independent

[ArBridgeman]

Summary

Use a library (e.g. pytest-randomly) or a nox session modification to run the tests in a random (yet reproducibly random order).

Verify that all tests can be run independent of one another by executing the random order at least 5 different ways.

Create a list of any tests that cannot be run independently and create follow up tasks to resolve:

• ./test/integration/formatter_test.py  test_complex_format_string affects test/integration/metadata_test.py test_list_indices. Without the former being run, the latter fails locally and in the CI.
