Feature request.

In order to make state channels more approachable we should allow the merchant subscribe to incoming client requests.
A coffee shop should be able to provide a service where the client start their app which should establish/re-establish a connection with the merchant where the merchant should enable automatically start the corresponding peer (channel client).

This would allow the following suggested end to end user flow.

1. Customer (bob) downloads app.
2. bob starts app, app targets predefined node where his fsm is hosted. Once app is started a channel open/reestablish is triggered
3. bobs action triggers an event at merchant (alice). Upon this action merchant opens the corresponding fsm using open/reestablish.
4. Bob and Alice now have an connection.

In the initial embodiment bob could provide contracts (if needed) and the alice app (web app) could be fairly simple.

Prerequisites for this to work is that there is a hosting node which can be reached by both parties. ref: aeternity/terraform-aws-testnet-api#23
