Redesign p2p around provision discovery

= Provision Discovery:Is an optional discovery technique for figuring out
if a peer supports the specific WPS option. For compatibility reasons,
we will now always use it during connection but at the same time support
devices that request to support connection without it

= State machine and UI redesign around the new interaction

= Specify config methods explicitly for compatibility
