Update to latest IPFS version - changes and testing needed

[makew0rld]

Discussed in chat here.

I asked some questions about issues I think we'd encounter in ipfs/kubo#7109, starting here.

[makew0rld]

I made a feature request that will enable nodes connected to the Internet and CJDNS to talk to CJDNS-only nodes: ipfs/kubo#7168.

I've made a feature request concerning nodes connected to Yggdrasil as well, which poses a different problem: ipfs/kubo#7169

[makew0rld]

If they're direct routes, then we should consider them as LAN nodes for the purpose of the DHT, and things should crossed_fingers work out. https://github.com/libp2p/go-libp2p-kad-dht/blob/master/dht_filters.go#L142-L150

This applies Yggdrasil direct peers, and it definitely something we should test and verify. Also, what would happen to the connections that aren't direct, like two-hop peers, etc?

v0.5.0 was released today, which supports only 2000::/3 being part of the IPv6 WAN. This solves any Yggdrasil issues.

I think we should upgrade, but disabling AutoNAT just in case. The main issue to be aware of is that nodes that are connected to the internet and the mesh will not be able to share files with the mesh. That is being tracked in ipfs/kubo#7168.

IPFS v0.5.1 and v0.6.0 have been out for a while. These changes should be looked at as well.

[makew0rld]

IPFS v0.7 was released today. The default multihash encoding has changed (Starts with Qm instead of k51) but that doesn't seem to be expected/hardcoded anywhere so it should be fine.
