REQ plugin about strfry HOT 1 OPEN

Hey, yeah this is a cool idea and would open up a lot of use-cases. You might even be able to do AUTH with it, as you suggest.

However, I'm considering the performance implications of this. Handling the REQ messages is on the critical path for all read requests, so the user-specifiable code would need a very low overhead to not impact relay performance. I think the way we do the write policy plugins would not work here, except for low-traffic relays.

I'm not totally sure what the answer is, but I think eventually we'll want to figure something out about this.
