Motivation

1. Customer cluster is shown as unavailable in rancher master for no obvious reason (no issue on network, firewall side)

2. Customer can receive update with fleet but cluster shown as unavailable and message is cluster agent is not connected

Redeploying cluster-cattle-agent

1. Get cluster ID for downstream cluster

2. On the management cluster find cluster ID with the below command to ensure that ID is good

   kubectl get clusters.management.cattle.io =><REPLACE_WITH_CLUSTERID>

3. Apply below command, this command should trigger redeploy of image and settings for cluster-cattle-agent

   kubectl patch clusters.management.cattle.io <REPLACE_WITH_CLUSTERID> -p '{"status":{"agentImage":"dummy"}}' --type merge

4. Wait for some time (15-30 min) to ensure that cluster return to available state
