Add new eslint rules (#2121)

The largest changes here are:
- enforcing single quotes for strings
- enforcing trailing commas where possible

In addition to those we have enabled several eslint plugins:
- plugin:requirejs/recommended, to enforce some conventions in require statements
- plugin:node/recommended, to enforce correct usage of various node.js APIs
- plugin:unicorn/recommended, which contains a pretty mixed bag of useful rules

This PR attempts to not change code behavior when possible.  In cases where fixing
existing code would change semantics, a linting exclusion has been placed in the 
code base to silence the error.  You can find these by searching for `eslint-disable-next-line`.
