Merge branch 'services_refactoring1' into 'master'
Services: code style fixes, minor refactoring ## What does this MR do? It contains code style fixes, minor refactoring and also it removes some unnecessary comments. Every comment require a support just like a regular code line and this is why we should avoid using comments everywhere unless it's really helpful. Martin Fowler said "Find comment and refactor the code around it" :) our code is not that bad so let's not spoil it with comments. ## Why was this MR needed? Because GitLab is a live example of awesome code. Let's keep up a good job :) See merge request !5112
