dynamic app routes

[amitu]

If an app is "mounted" on say /app/, all URLs of that app start with /app/, and that app wants a URL that looks like /foo/, meaning does not start with /app/, we are introducing dynamic app routes feature. To use this feature the app has to use ft-sdk to call the host provided add-dynamic-app-route etc. We will have CRUD methods to add / update / remove dynamic routes.

These routes will be managed by host and will be used to do routing. The app can add the source and target URLs when adding a dynamic app route, and if there is hit to the source url, the server will assume the target url was hit. Eg /app/ can add source=/foo/ and target=/app/foo/ and when request to /foo/ comes, we will process the request as if the request to /app/foo/ had come.

The app can choose to redirect to another URL, or show content at the source url.
