Yannick Welsch be19ccef57 Discard stale node responses from async shard fetching (#24434)
Async shard fetching only uses the node id to correlate responses to requests. This can lead to a situation where a response from an earlier request is mistaken as response from a new request when a node is restarted. This commit adds unique round ids to correlate responses to requests.
