Actual BYOF

[nturinski]

It seems like the service can actually hook a static web app with an existing function app, letting users actually BYOF.

We should be able to do the same

Entry points could be:

1. In the prompt, show any local projects or ask if they want to link it to an existing function app
2. If there is no function API associated with the SWA, have a node that lets them link a function app up
