Sam Swarr d5445d5fbc Add ability to silence packager logs to stdout
Summary:We use a few different modules to output logs to stdout when building a bundle with the packager:
- ##js/react-native-github/packager/react-packager/src/Activity/index.js##
- ##js/react-native-github/local-cli/util/log.js##
- ##https://www.npmjs.com/package/progress##

This diff also adds a ##silent## option to the packager ##Server##, which, when ##true##, will not create a ##progress## instance for the transformer.
