Ability to exclude linting

[decrn]

Hi. Something like

// eslint-ignore-line would be tremendously helpful.

Hey, thanks for the request! Would indeed be a very nice and welcome feature. I just checked, but comments (# test) don't seem to be available in the AST of graphql-js.

I'll see if there is an easy way to support this, could probably take some time though.
