This PR brings the fix https://github.com/paritytech/substrate/pull/13396 to polkadot-sdk. In the past, due to insufficient inbound slot count on polkadot & kusama, this fix led to low peer count. The situation has improved since then after changing the default ratio between `--in-peers` & `--out-peers`. Nevertheless, it's expected that the reported total peer count with this fix is going to be lower than without it. This should be seen as the correct number of working connections reported, as opposed to also reporting already closed connections, and not as lower count of working connections with peers. This PR also removes the peer eviction mechanism, as closed substream detection is a more granular way of detecting peers that stopped syncing with us. The burn-in has been already performed as part of testing these changes in https://github.com/paritytech/polkadot-sdk/pull/3426. --------- Co-authored-by: Aaro Altonen <a.altonen@hotmail.com>

title: Detect closed notification substreams instead of evicting all peers

description: |
|
|
Replace eviction of all peers when syncing has completely stalled with a more granular
|
|
detection of notification substreams closed by remote peers.
|
|
|
|
This change is expected to make the _reported_ peer count lower, as before this change
|
|
the number also included already closed substreams. Nevertheless, the currently reported
|
|
number should be seen as the real number of working connections.
