Remote storage uploadFile should not have a dependency towards appConfig https://github.com/adobe/aio-lib-web/blob/master/lib/remote-storage.js#L110

As we do for config.s3.folder we should pass specific values and not have remote storage depend on the config object https://github.com/adobe/aio-lib-web/blob/master/src/deploy-web.js#L45
