Can you please add details about the environmental variables support in the Argo CD CR for each component.

For Example:

kind: ArgoCD
...
...
spec:
  controller:
     env:
       - name: foo
          value: bar

Hi @iam-veeramalla , I updated PR as per comment. I still have a question, about the custom environment variables, there’s already a page that has the information. Aren't these env variables part of ArgoCD, not part of argocd-operator?

As discussed I kept the information on this environment variable page as a good summary of environment variables available on argocd-operator. Thanks for the confirmation.
