Description

test_statestore.py does several python tests that build statestore clients to unit test statestored. Based on the logs from statestored, these test clients persist long after the test_statestore.py has completed. They continue to exist for the rest of the invocation of pytest.

This results in a large amount of logging like this:

This does not seem to impact any tests, but it does produce some log spew in the normal output.
