'argocd version --client' fails if no valid Kubernetes context after using 'argocd login --core'

If you are trying to resolve an environment-specific issue or have a one-off question about the edge case that does not require a feature then please consider asking a question in argocd slack channel.

• I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

After logging into an Argo CD instance running in an EKS cluster with argocd login --core, I can no longer run argocd version --client without having a valid Kubernetes context to the EKS cluster.

The assumption is that argocd version --client would not require access to the Kubernetes API at all using --client.

To Reproduce

To successfully login with --core:

$ aws eks update-kubeconfig --name xxx --alias xxx
Updated context xxx in /Users/donovan/.kube/config

$ kubectl config set-context --current --namespace=argocd
Context "xxx" modified.
$ argocd login --core
Context 'kubernetes' updated
$ argocd version --client
argocd: v2.1.3+d855831.dirty
  BuildDate: 2021-09-30T22:11:24Z
  GitCommit: d855831540e51d8a90b1006d2eb9f49ab1b088af
  GitTreeState: dirty
  GoVersion: go1.17.1
  Compiler: gc
  Platform: darwin/amd64

Now, without any Kube context:

$ argocd logout kubernetes --core
Logged out from 'kubernetes'
$ rm ~/.kube/config
$ argocd version --client
Error: invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable

Or with an invalid/expired (using assumed IAM Role tokens) Kube context for the EKS cluster:

$ argocd version --client

# just hangs...

Expected behavior

argocd version --client to return the argocd version regardless of Kubernetes context.

Version

$ argocd version --client
