Store connection direction for peers

[andrewheadricke]

I would like to see in ipfs swarm peers or even ipfs swarm peers -v the direction of connection for each peer. I basically want to know which peers connected to me, and which peers I have initiated a connection to.

I am trying to more closely manage my list of peers and this information would be very useful.

I'm guessing this would need to be implemented at the libp2p level?

We now actually store this. Internally, you can call Stat() on a connection to get information like direction (well, at the moment, that's just about all you can get). We should definitely expose this.

Hey @Stebalien, can I try to solve this?

Go ahead.

Hey @Stebalien, I add the direction of connection behind the multiaddr, when i use ipfs swarm peers -v. like the follow:

/ip4/158.69.53.41/tcp/4001/ipfs/Qm... n/a outbound
/ip4/159.89.147.117/tcp/4001/ipfs/Qm... n/a outbound
/ip4/162.252.217.94/tcp/4001/ipfs/Qm... n/a outbound
/ip4/163.172.89.219/tcp/4001/ipfs/Qm... 239.373985ms outbound
  /ipfs/kad/1.0.0
/ip4/165.227.15.228/tcp/4001/ipfs/Qm... n/a outbound
  /ipfs/bitswap/1.1.0
  /ipfs/kad/1.0.0

What do you think of it？
