[BUG] cluster state stuck at "Waiting for etcd snapshot creation management plane restart probes"

[bpedersen2]

Rancher Server Setup

• Rancher version: 2.8.4
• Installation option (Docker install/Helm Chart): docker

Information about the Cluster

• Kubernetes version: 1.28.9-k3s
• Cluster Type (Local/Downstream): Downstream

Describe the bug
After a node crash the cluster state is stuck at
'''Waiting for etcd snapshot creation management plane restart probes'''

All operations can be performed normally, so this is more a cosmetic bug

To Reproduce
Not really known

Expected Result
cluster recovers fully from node crash after some time or a manual workaround to reset this state.

Additional Informations

both rancher upgrade 2.8.3 -> 2.8.4 and k3s version upgrade (1.27.x -> 1.28.x) went smoothly, but did not reset this message.

It seems this was caused by outdated certificates on one node. After clearing the old certs (following #41125 (comment)) the node updated successfully.
