Run this on CI. Catches non-deferred .Close() calls, understands deferred func literals containing simple .Close() calls as well as simple defer statements

This is great, few things:

1. Nothing exists in golang-ci for this very case? I'd prefer to push the work of maintaining such a script to golang-ci people
2. This code is great but doesn't actually add it to our CI, shouldn't we do that in this PR here

Should add to makefile as well
