Fix CI jobs and integrate helm into the repo.

CI jobs are working with the addition of two helm jobs. When a tag is created, the helm-package job is triggered which creates and pushes the helm package from the chart located at deployment/helm. The Chart.yaml there needs to be updated with a new tag, before it's initiated. A similar deployment flow like before, only know the Chart.yaml is in the same repo, rather than a separate one.
