🐞 Investigate KubernetesClient credential usage in Control Panel

[michaeljcollinsuk]

Describe the bug.

There is a KubernetesClient wrapper class in Control Panel, that attempts use a users ID token as its auth credential when making API calls. I am not sure that this is working as intended, so we should spend some time to dig a bit deeper about:

1. What the original intention of using a users ID token was rather than the service accounts credentials
2. How this is intended to work and determine if this is working or not
3. Amend the implementation as necessary

To Reproduce

1. Run the control panel locally
2. Update the code where the KubernetesClient is used (e.g. tool restart) and pass an arbritary string rather than a real ID token
3. Trigger the action in the browser (e.g. tool restart)
4. If the restart triggers successfully, this indicates the ID token being passed in the KubernetesClient is irrelevant

Expected Behaviour
