Harmonise some naming/abbreviation patterns
From: https://gitlab.hzdr.de/hifis/software-services-organization/issues/44.
@erxleb87: Please feel free to WIP this, update the title to match that ticket and add more commits to implement whatever will be decided there, if you think that a single MR for the "naming/abbreviation pattern" is better.
