feat: peer scoring strategies for light protocols

[weboko]

This is a feature request

Problem

Peer scoring for light protocols should improve overall quality of peers being used by a node. This should drive satisfaction from the service provided as well as perceived reliability.

Proposed Solutions

Filter scoring:

• Subscribe to 2 peers and compare if 1st broadcasts messages faster than 2nd;

Filter scoring (with use of Store):

• Check if any of present subscriptions misses any messages by using store pings;

Light push scoring (with use of Filter):

• Check if a message sent through peer A was relayed from any of the Filter subscriptions;

Other strategies that might be used(each should be discussed):

• Pretense of Relay protocol is beneficial for other protocols;
• If we know IP we can try to decide if a peer is close to us geographically (note that these should not be the only peers a node is using but some);
• Investigate if libp2p ping can be used to measure latency;
• Blacklist peers that drop connection with us more than once;
• Monitor errors during Filter ping / Filter subscribe / Lightpush send and other operations within protocols - decrease score for such peers;

Notes

Decoupled from discussions in #1463

[danisharora099]

Peer scoring for light protocols should improve overall quality of peers being used by a node.

scoring was decided to not be introduced for the scope of js-waku currently (ref: #1463 (comment), #1463 (comment)) as js-waku is a relatively short-lived connection when compared to its full-node counterparts where scoring offers a much more substantial advantage.

If we know IP we can try to decide if a peer is close to us geographically (note that these should not be the only peers a node is using but some);
Investigate if libp2p ping can be used to measure latency;

We do this part of finding connections to peer currently: peers with lowest latency are given priority

Agree that we have no deliverable in this issue.
I think we should revisit it sometime in the future.

Iceboxing for now
