cmd/k8s-operator: require namespace config (#14648)

Browse Source 
Most users should not run into this because it's set in the helm chart
and the deploy manifest, but if namespace is not set we get confusing
authz errors because the kube client tries to fetch some namespaced resources
as though they're cluster-scoped and reports permission denied. Try to
detect namespace from the default projected volume, and otherwise fatal.

Fixes #cleanup
