Post our recent move to using Python3.9 (#2692) we have the following while runing our tests using rock-tests runner in PyCharm:

/opt/rockstor/.venv/lib/python3.9/site-packages/django/utils/version.py:98: DeprecationWarning: distutils Version classes are deprecated. Use packaging.version instead.
  loose_version = LooseVersion(version)

This looks to be a change coming with Python 3.10 re: PEP 632 – Deprecate distutils module
