@djazayeri @mseaton
I had to move #249 to this one.

The previous PR was already marked as "OK" by @mseaton, @djazayeri could you take a look at this one?

@ibacher @mseaton @dkayiwa @djazayeri

we would like to get back to this and make the code ready for merging. We applied previous remarks from code review. Can you take a look at this once again?
This PR and openmrs/openmrs-module-reportingrest#33 are related to each other and together constitute backend for Reports page in O3 UI - openmrs/openmrs-esm-admin-tools#45 (this UI PR has to be adapted after merging backend PRs)
