Add new k8s_proxy scope for PATs
#409028 (comment 1487010922) has more context
Proposal
Do something like !124074 (diffs) (as an example of a recent addition of scope) for a new k8s_proxy
scope.
This should be a behind a feature flag. We don't want this to show up in the UI unless the feature flag is enabled and it will actually do something.
