Support prettier v1.6.0 config

[jaydenseric]

Prettier v1.6.0 is out, and it implements cosmiconfig for options.

This plugin currently requires prettier config to be set within ESLint config. It would be awesome to deprecate this and let prettier derive the config itself.

Seems reasonable to me. It looks like prettier exposes a resolveConfig function for getting a config, so I think it should be pretty simple to let prettier handle config resolution.

Actually, I think this is blocked by prettier/prettier#2722.

@not-an-aardvark since it has been merged, I guess we have to wait for the next prettier release ?

[not-an-aardvark]

Yes, that's correct.

Tracking for 1.6.2 which will include .sync() prettier/prettier#2804
