Dependency checker

[pragya91]

Attempt to fix the depcheck tool, that can be used to report or fix the unused or misplaced dependencies in the repo.

I'll look more deeply later, but one high level question is: could this be a policy instead? fluid-build doesn't seem like the right place to put this. Instead, you could factor out the check code needed into build-cli alongside the other repo policies.

Also consider adding config options. That way we can configure and document things in one central place. Especially if there are hardcoded lists of expectations, for example.

Worth a look if you haven't seen it: https://www.npmjs.com/package/depcheck
