K3s upgrade via watch over file change of static file and manifest and triggers helm-controller for change. It seems reasonable to only allow upgrade traefik v1->v2 when there is no existing custom traefik HelmChartConfig in the cluster to avoid any incompatibility. Here also separate the CRDs and put them into a different chart to support CRD upgrade. Signed-off-by: Chin-Ya Huang <chin-ya.huang@suse.com>
