Actor input/output binding support

Functions should be able to send one-way messages to actors using output bindings and also fetch the state of an actor using input bindings.

This issue needs more clarification, @msfussell and I will discuss the scenario before it can be implemented.

@cgillum do you see a chance that actor reminders fire a Function trigger like e.g. DaprActorReminderTrigger
