Pass additional CAs via calico-management-additional-cluster-connection secret and set variables for voltron to pick up that new CA. The new CA will be using secret calico-management-cluster-connection and old CA will be kept as backup in calico-management-additional-cluster-connection secret. Once all managed clusters have been migrated to have client credentials generated by the new CA, we will delete the old CA by deleting secret calico-management-additional-cluster-connection.
