Swarm: add fn ban_peer_id_with_duration

[hanabi1224]

Description

Currently ban_peer_id bans a peer for the entire lifetime of the swarm unless unban_peer_id is called. It would be great to have another ban_peer_id_with_duration API that automatically unbans the peer after the specific duration.

Motivation

The peers being banned may "correct" their behavior and we would give them a chance to reconnect after a while so that we can re-evaluate them

Requirements

1. the API accepts an additional Duration parameter
2. automatically unban the peer after the specified duration
3. the API change should be backward compatible, requiring only patch version bump

Open questions

Are you planning to do it yourself in a pull request?

Maybe.

If I am not mistaken, you can already achieve this behavior by calling unban_peer_id on Swarm once an external timer fired.

Unless there is a majority of users that would need this feature, I would advocate for this to live outside of rust-libp2p as described above.

Long term I advocate for making most of the connection management generic. See #2824.
