set resolver to dockers internal dns for first 30 seconds

[rwblair]

If the swagger containers hostname wouldn't resolve nginx would fail to start. I put in the set directive by its proxypass to get around nginx trying to do the hostname lookup on startup. Nginx was complaining about not having a resolver when you visited /api/swagger. Made change according to this:

Pushed to deepdream, no longer getting 502 error, But there is something else wrong now, swagger ui is blank with lots of JS errors like:

Uncaught ReferenceError: SwaggerUIBundle is not defined

[adelavega]

@rwblair I think theres' something wrong w/ nginx bc it doesn't seem to be loading the json files and css files for swagger ui.

looks like maybe they're routed instead to the wrong container (neuroscout?). can you take a look?

[adelavega]

^~ vs ^ vs none? otherwise let's merge this so it fixes swagger-ui and we can fix the problem of restarting nginx (when swagger fails) in another PR later.
