After setting up basic CI with linting, need in refactoring became evident.
The code is brought in accordance with PEP8 standard and few improvements were also made,
notably lazy logging is now used, so the logger should not bring too much overhead
(this should be visible with test bages). The CI file was pre-pushed to the develop in order to have convenient badges on the gitlab page. Sorry
If there're any comments to CI file, the can be addressed in the current MR,
however I'd consider it to be a pretty good basic template. As soon as eos website for service account will be created, the docs deployment job can be used.
