Day 2 propagation of Annotations from Klusterlet spec to ManagedCluster #1210
Description
Describe the enhancement
The klusterletChartConfig.Klusterlet.RegistrationConfiguration.ClusterAnnotations is currently only used during spoke registration. However it would be useful to propagate updates to these annotations during day 2, for example as part of a Klusterlet upgrade.
Please consider implementing a periodic sync of annotations from Klusterlet spec to the ManagedCluster. To minimize disruption to existing deployments, the 2 sets of annotations can be merged.
