Hole punching over takes over 5 seconds between peers

What's wrong

Given the following scenario:

• 1 go-libp2p peer with a public IP
• 1 kubo go-libp2p peer behind NAT with a circuit relay 2 reservation over QUIC
• circuit relay v2 peer

Holepunching take just over 5 seconds even though the latency between the peers is no more than 150ms.

This problem was observed in the Vole CheckBitswapCID method.

Due to a context deadline shorter than the ~5 seconds it takes for the hole punching to succeed, that is defined in the Boxo Bitswap implementation, a workaround was added to open a stream before with a longer deadline. Below are debug logs showing the connection succeeding using this approach after a little over 5 seconds.

logs

Below are the logs from a feature branch of Vole, whereby we open a stream right after opening the connection to force hole punching
