Add support for transient services depending on scoped services.

[DDEfromOR]

1. Unblocks users designing transient bots with scoped dependencies, by creating a new scope for each request in the same manner an MVC controller would.

2. Allows for passing in of OnTurnError logic via the application extension for bots using named pipes.
