chectl cannot find a workspace pod while injecting kubeconfig

[azatsarynnyy]

Describe the bug

chectl workspace:inject -k looks for a workspace pod by label che.workspace_id. But it gets incorrect pod since there's another pod with the same label may present - che-jwt-proxy.

Need to change the way of looking for a workspace pod relying on the label che.original_name=che-workspace-pod.

Che version

• latest
• nightly

Steps to reproduce

Call chectl workspace:inject -k. It should find a single running workspace pod. But it reports:

  ✔ Verify if namespace che exists
  ✖ Verify if the workspaces is running
    → More than one pod with running workspace is found. Please, specify Che Workspace ID.
    Injecting configurations
 ›   Error: More than one pod with running workspace is found. Please, specify Che Workspace ID.

Even after specifying the correct workspace ID, chectl tries using incorrect pod:

  ✔ Verify if namespace che exists
  ✔ Verify if the workspaces is running
  ✔ Injecting configurations
    ↓ injecting kubeconfig into container verifier [skipped]
      → Command failed with exit code 1 (EPERM): kubectl exec workspacedwptaf8bkgtune92.che-jwtproxy-6758c84d55-dqr4m -n che -c verifier -- mkdir //.kube -p
