Add Helm-2to3.gitlab-ci.yml to Auto DevOps

Merged Hordur Freyr Yngvason requested to merge add-helm-2to3-ci-template into master

What does this MR do?

Adds the previously external Helm-2to3.gitlab-ci.yml template to GitLab and includes it in Auto-DevOps.gitlab-ci.yml.

Users without a .gitlab-ci.yml also need to be able to migrate. For some users, adding a .gitlab-ci.yml may not be an option.

  • The jobs are only included when a very specific CI/CD variable is present.
  • The jobs are safe to run multiple times.
