Hello all, I have a few questions about the Sharding mechanism in Fleet. I've also opened a related issue for this here: https://github.com/rancher/fleet/issues/4183. We would like to use sharding for all resources managed by Fleet, including Clusters, GitRepos, Bundles, and BundleDeployments. 1. Is there a performance report that shows what level of scaling can be reached with sharding enabled? 2. I noticed that in the Rancher code, when it creates Fleet cluster resources, it filters out any labels with a `cattle.io`prefix. This prevents the label for sharding from being propagated to the Fleet cluster resource from the Rancher cluster resource. Is there a reason Rancher prevents this, or is this a bug? You can see the code in question here: https://github.com/rancher/rancher/blob/main/pkg/controllers/provisioningv2/fleetcluster/fleetcluster.go#L199. thanks.
