request if User has echo buttons on launch
Currently you need to do rollcall to find out if a user has echo buttons. But it seems like a bad user experience to do button roll call or ask a user if they have buttons. If we could get sent something on launch saying user has used buttons before or connected them previously or currently has them connected then we know we can try roll call or ask them if they want to use buttons.
Current solution seems to be to build a separate skill for buttons.
