Chart refactor for passthrough + redis-bb

General MR

Summary

• move global to top level yaml structure (required for upstream helpers templating)
• move redis-bb to top level yaml structure
• remove SSO config as it is baked in from upstream umbrella values (see changes: big-bang/bigbang!6528 (diffs)) ^ note: these will be integrated into the argocd bb.2 tag as changes upstream. Current SSO values are utilized in bigbang umbrella addons.argocd.sso section, and should not be affected.

Upgrade Notices

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

Current Values

configs:
  cm: 
    oidc.config: |
      name: keycloak
      ...

Updated Values

upstream:
  configs:
    cm: 
      oidc.config: |
        name: keycloak
        ...

This change does not apply to bigbang specific values in the chart, i.e. awsCredentials, istio, monitoring, networkPolicies, upgradeJob, bbtests, openshift, and redis-bb. Note that global is also preserved due to an upstream requirement.

• SSO is now propagated through the proper values.yaml channels in upstream argocd chart. Users should refer to upstream chart for any additional SSO configuration, specifically argo-cd/templates/argocd-configs/argocd-rbac-cm.yaml and argo-cd/templates/argocd-configs/argocd-cm.yaml found here.
