Add configs for prettier, adjust eslint rules

For prettier, there are some config changes between v2 and v3.  The
new default for tailing commas changed causing a lot of breaks.  Use
the v2 default of "es5" for now.

A few eslint rules changed to warnings since there are a lot of them
and we don't want to fix those now.
