run tests on python3.10 and remove disutils
As of python 3.10 disutils is depreciated and this is causing errors on CI https://gitlab.syncad.com/hive/haf/-/pipelines/61249
Temporary fix is suppressing depreciation warning on tests but long term solution is to replace disutils with smth else (possible own implementation of strtobool)
Also all tests of test_tools should be run using python 3.10 as this is default python version on ubuntu 22.04 - base image for hived (previously this was ubuntu 20.04 and python 3.8). Depreciating disutils is one of changes in python 3.10
