weird errors when expanding test coverage for openeo_driver.utils.logging

[soxofaan]

While working on logging tweaks for Open-EO/openeo-aggregator#74 I expanded openeo_driver.utils.logging feature set a bit and improved related test coverage.

On jenkins, some tests in https://github.com/Open-EO/openeo-python-driver/blob/master/tests/util/test_logging.py (using the pytester fixture) started to fail because of weird warning (?) in the output of some test scripts:

Error processing line 1 of
/usr/local/lib/python3.8/site-packages/distutils-precedence.pth:

  Traceback (most recent call last):
    File "/usr/lib64/python3.8/site.py", line 169, in addpackage
      exec(line)
    File "<string>", line 1, in <module>
  AttributeError: module '_distutils_hack' has no attribute 'ensure_shim'

we already had that problem in #193 apparently

problem is discussed at pypa/setuptools#2983 and pypa/setuptools#2957

upgrading setuptools in the jenkins setup to a recent enough version is probably going to take some time, so it's probably best, to just ignore these warnings for now

closing this one for now, warnings are now being workarounded
