Proposed Feature

A global configuration block akin to the argocd one: https://github.com/argoproj/argo-helm/blob/f42e0e1fd586d48459d99db69e65f2540a5cd209/charts/argo-cd/values.yaml#L38-L149

Motivation

This is quite... a lot to set to have a global toleration on a node group.

api:
  tolerations: 
    - key: "CriticalAddonsOnly"
      operator: "Exists"
  oidc:
    dex:
      tolerations: 
        - key: "CriticalAddonsOnly"
          operator: "Exists"
controller:
  tolerations: 
    - key: "CriticalAddonsOnly"
      operator: "Exists"
managementController:
  tolerations: 
    - key: "CriticalAddonsOnly"
      operator: "Exists"
webhooksServer:
  tolerations: 
    - key: "CriticalAddonsOnly"
      operator: "Exists"
garbageCollector:
  tolerations: 
    - key: "CriticalAddonsOnly"
      operator: "Exists"

Suggested Implementation

Follow the ArgoCD chart and have some things that can be globally set on all pods.
