Implement kiosk multiple apps feature. This includes:

1. Add new manifest keys in the manifest file of the primary kiosk app to configure secondary kiosk apps.
2. Implement the work flow for primary kiosk to download and install secondary apps before its first time launch.
3. Expand FakeCWS to support multiple kiosk apps' update check.
4. Move the hard coded local extension cache director to chromeos path service so that it can be created in testing environment.
