Last inspect on all modules

- Mainly focussed on spelling mistakes (e.g. schema set instead of schemaset)
- Removed some unused code (overloaded but unused interface methods)
- spelling issues resolve in many timed method (names) by adding full stops.
  I think this only affects Graphana dashboards etc and should be OK
- Changed timeformat descriptions to say just "ISO standard format"
- Fixed latest SonarQube warnings
  (removed test from MultiPartFileUtilSpec as the scenarios are correctly unit-tested in ZipFileSizeValidatorSpec)
