Support Circuit Relay v2 for Hole Punching

[lidel]

After libp2p/js-libp2p#1029 ships, and we have v2 relays on the network, js-ipfs should have v2 client support enabled to be able to do the hole punching (https://github.com/libp2p/specs/blob/master/relay/DCUtR.md).

Hole punching is a big blocker for getting js-ipfs to work reliably for p2p use cases. 😅

Currently stuck with using the npm-go-ipfs repo since stuff often doesn't resolve or takes a very long time.

• LBL will add this in js-libp2p
• This will be supported in Helia
• This probably won't be enabled in js-ipfs

@tinytb What is LBL?

For anyone stumbling across this, the good news is that Circuit Relay V2 is being implemented in js-libp2p libp2p/js-libp2p#1533 so that NAT hole punching is available for the JS part of the stack.

LBL is Little Bear Labs
