Add global standard labels like other charts

See gitlab-com/gl-infra/k8s-workloads/gitlab-com!2618 (comment 1328705148) and !6 (closed) . I already started the work in !6 (closed) but it doesn't work and may not be the right direction.

We had to disable some linting on our helm chart because it didn't define the labels type,tier,stage,shard. It will likely be beneficial for monitoring and other automation purposes to ensure we have these labels in our chart. We could either try to redefine the helpers that pull these values from global in our chart or hardcode them all in the values.yaml for our chart again or maybe there is a more elegant approach we can look into.
