Don't use editorconfig to check for indentation

[matejak]

Fix editorconfig - make rules effective for all files, not just the top project level.

The main motivation is to stop enforcing 4-space indentation in Python, as it is not valid in some cases.

Research has shown that the editorconfig is respected - setting the indent_size to 2 fixed many issues. Sadly, the absence of indent_size = 4 still results in requiring 4-space indentation - that's probably some sort of a default value.
Working around by setting indent_size = 1 would not work well either, as editors that use editorconfig would pick this setting up as well, which would mess up the editor workflow for the user.

The only solution is to explicitly switch the check off as described in https://editorconfig-specification.readthedocs.io/

@Mab879 Could we merge this? It would fix a lot of CodeClimate false positives
