Tests manipulating credentials are not properly isolated from one another #3071
Description
Description
All test manipulating credentials are loading and saving into the default docker config location.
This increases significantly the risk of cross-test pollution, false positives / negatives, and definitely prevents parallelization of tests.
Each test that relies on reading or saving credentials must use a dedicated temp location instead.
