Companion Device App showing in Settings

Added a feature that users are able to see/remove the apps' associations
in Settings/Connected devices.
It will display the icon of the associations app, app's name and a button
that users are able to remove the associations. Also it will pop up a
dialog alerting user before remove the associations.
