Speed up content routing with bloom filters, car pools, and consistent hasing

[b0xtch]

We currently use the typical stack in libp2p for content routing, which includes, Kademlia, Gossipsub, and Bitswap. To speed up content routing, we propose using a custom implementation of bloom filters for IPLD data that lives independently on each node and can be shared or pulled from one node to another. Other discussions have also proposed the following to work here by Fission.
