A recent change to build-helm-charts.sh broke the CENGN build. New arguments must now be supplied. On behalf of those of us that maintain automated build environments, I have an urgent request 1) If possible, make the change backward compatible.  No changes to build scripts required for 'normal' use cases. 2) Notify the community of the change through the starlingx-discuss list before it goes WF+1    - include the [build] tag in the subject    - if the change is not backward compatible, include [action-required] in the subject    - briefly describe your changes, but with sufficient detail that folks know what changes they need to make to successfully build an iso, docker images, helm charts, etc.    - point to a wiki/documentation where greater details can be found.    - point to the gerrit code review. 3) notify folks through the IRC channel.  Point to the starlingx-discuss posting.
