The upstream Helm chart repos have moved permanently, causing a failure when running "make helm-serve": 'Error: error initializing: Looks like "https://kubernetes-charts.storage.googleapis.com" is not a valid chart repository or cannot be reached'. This change skips the chart refresh, since the upstream charts are not used anyway. Change-Id: Ic146e09dca6a7d72607a794984376d0fa9bc5475
