Upgrade Notices

• Refactoring package with passthrough pattern. Passing values to the gitlab runner upstream chart will require an additional layer of overlay: addons.gitlabRunner.values.upstream An example for update would look like the following:

Current Values

image:
  registry: registry1.dso.mil
  image: ironbank/gitlab/gitlab-runner/gitlab-runner
  tag: v18.0.2

Updated Values

upstream:
  image:
    registry: registry1.dso.mil
    image: ironbank/gitlab/gitlab-runner/gitlab-runner
    tag: v18.0.2

This change does not apply to bigbang specific values in the chart, i.e. istio, monitoring, networkPolicies, autoRegister, bbtests, openshift, and extraContainers.
