chore: enable all pylint checks excluding the violated ones
What does this merge request do and why?
This MR enables all pylint checks excluding the violated ones. Docs: https://pylint.pycqa.org/en/latest/user_guide/checkers/features.html
It also fixes the single invalid-name check violation. Now invalid-name check can be enabled. It can catch the variables/function names that are using invalid naming like camelCase.
