@raulk done -- moved it to an extension spec and left the original spec unmolested.

This is a functional extension to gossipsub 1.1 (does not affect the protocol) to introduce a circuit-breaker-like feature to defend against spam attacks.

It's a working draft, and we're testing it out in the Filecoin Space Race network. Might be worth to adopt in Eth2 too.

Reference implementation here: https://github.com/libp2p/go-libp2p-pubsub/pull/384 Expect it to be fine-tuned over the next days.
