This is consistent with what we're pretty much already doing, and saves us from making the request during code review.
These were all autofixed and most of them seem easier to read. Some in the legacy services should be rewritten in more legible forms during refactor (ie using intermediate variables, or using request’s qs option). There are some in helper functions and elsewhere that should get rewritten separately. I don't want to change them in this PR because the changes will get lost in this diff, though we could identify them here and fix them before or just after.
We use arrow functions in most places; this enforces it.
Passing arrow functions to Mocha is discouraged: https://mochajs.org/#arrow-functions
This was a mix of autofixes and hand adjustments.
Because I despise nitpicking stuff like indentation and spacing in pull request comments, I'd like to nudge forward our automated style checking, at least for new files being added.
I don't want to totally rewrite server.js just to get automated style checking… the blame tracking is just too useful. So let's it's just take care of that when we start splitting it out.
