Low gossipsub score due to p7

[twoeths]

Describe the bug

This fix ChainSafe/js-libp2p-gossipsub#385 helps minimize broken promises for a while, however since Jan 25 we catch less promises from duplicate and there are more broken promises

This is monitored from a mainnet node subscribing to all subnets. Update: this happens on all mainnet nodes

Expected behavior

Low broken promises

[twoeths]

On mainnet, the percentage of promise broken ratio is quite high since Jan 25

[twoeths]

since Jan 25 on mainnet nodes there are more Nimbus peers

there are a lot of IWANT promise that's never delivered since then

this PR also confirms Nimbus peer score is low #5094 (comment)

need to work with Nimbus to improve its gossip peer score

[twoeths]

Some issues/PRs in progress in order to debug this issue:

• persistNetworkIdentity cli option #5175
• Add logger option js-libp2p-gossipsub#406
• Delayed IWANT messages from Lodestar to Nimbus js-libp2p-gossipsub#408 ===> this is the root cause

[twoeths]

This issue disappeared since Mar 06. Also Nimbus had a fix to not limit responding only first 25 message ids in response to gossip Iwant request

The number of Nimbus peers is also not consistently high as earlier: some have very few Nimbus peers, some have up to 50% Nimbus peers

Closing the issue.
