enable code linting check for all supported Python versions

run linting tests for all supported python versions

[JensTimmerman]

seems to work, tests fail because we're now catching errors:

./easybuild/tools/configobj.py:2026:55: F812 list comprehension redefines 'line' from line 2014

@boegel This looks ok to me, and the caught error might need to be fixed ....

[akesandgren]

@JensTimmerman could you do "eb --sync-pr-with-develop 3725 --pr-target-repo easybuild-framework" on this one to make sure it's up to date.

@akesandgren that didn't seem to work for me, I just merged develop into this branch, if that also works for you?

@JensTimmerman could you do "eb --sync-pr-with-develop 3725 --pr-target-repo easybuild-framework" on this one to make sure it's up to date.

It did exactly what it needed to do, make sure that it applies on top of current develop HEAD and re-kick the test suite.
Adding the commit for 3.10 would have caused the same thing I was after, i.e. re-running the tests.

You could also add a small fix for the line redefined problem it detects, not sure what @boegel would accept here but I think
easybuild/tools/configobj.py:2026 can be changed to use "ln" instead of "line" without too much complaints from him...

[JensTimmerman]

ideally this only get's skipped for python2, but I couldn't quickly find a good filter for this case.

[boegel]

fixed in a2ec58b

Thanks a lot @JensTimmerman!
