This is incorrect. The probes server can be exposed whether NTH runs as a daemonset or as a deployment and is not related to IMDS mode. Our default configurations here only enable it for the daemonset, not the deployment, but that is not a technical limitation.
Indeed, our release artifacts explicitly include an aggregated YAML configuration with probes server enabled in Queue Processor mode as a deployment (see the artifact all-resources-queue-processor.yaml from any v1 release). Here's the code that generates that file:

To be more correct, let's remove "for the Daemonset", since the probes server can be used in a deployment and is not related to IMDS mode.

Issue #, if available:
None
Description of changes:
Remove configuration settings that don't affect Queue Processor mode (assuming #743 merges) from the Deployment template, so that they don't act as red herrings.
Document the settings that only apply to IMDS mode.
