Abort live sync / sync_render when a dependency updates

[thruflo]

So, you can provide a Shape or stream or subscribe function that automatically knows when to invalidate and re-run a live shape request which depends on some data/params.

From:

conn
|> Phoenix.Sync.Controller.sync_render(params, query)

To:

conn
|> Phoenix.Sync.Controller.sync_render(params, {queryFn, dependencies: [Model.Task]})

So shape definitions can be dynamic with function and dependency.

This was implemented as interruptible shapes
