Gossipsub v1.1

Background

Gossipsub is a pubsub router implementation that succeeded Floodsub as the default pubsub router for libp2p and IPFS. Over the last months, the IPFS/libp2p teams have been working on extending the initial version of gossipsub to improve bootstrapping and protocol attack resistance. The extensions change the algorithms that prescribe local peer behaviour and are fully backwards compatible with v1.0 of the protocol. Peers that implement these extensions, advertise v1.1 of the protocol using /meshsub/1.1.0 as the protocol string.

I created this Issue to track the gossipsub update work and provide visibility for the libp2p@0.29 release work. Feel free to change/decouple milesones if it is easier for your side. Meanwhile, we are going to start working on the signed peer records as we need this to gossipsub and rendezvous (#651).

Done and released in 0.29 🎉
