For pecan to support existing agent scheduler controllers, a couple of shim pecan controllers need to be added. These shim controllers will be used if there are extensions that have legacy controllers that have not been registered. The shim controller is just a passthrough to those legacy controllers. This may have the added benefit of support existing out of tree extensions that have defined their legacy extension controllers the same way. Changes to how the router(s) controllers determines whether something is a member action has been changed a bit to support this.
