Pipeline stage to build and push helm chart to container registry. #1416
Description
Summary
I would like to have pipeline stage which can build helm chart and push the same to public/private container registries.
Motivation
Currently we have stages in pipeline to build Docker image and push it to the public / private container registries but we don't have stage which can build and push the helm charts.
Proposal
The stage will spin-off new kubernetes pod with image having helm installed, it will build the helm chart from the folder path provided in input. The built helm chart can be pushed to container registry.
