Document deployment, metrics dependencies, health checks, and troubleshooting for the self-hosted Function Autoscaler. Update observability and Helmfile guidance for bundled VictoriaMetrics and existing metrics backends. Signed-off-by: Bora Oztekin <boztekin@nvidia.com>
📝 WalkthroughWalkthroughThe documentation updates define profile-based observability, VictoriaMetrics or external backend configuration, Helmfile deployment requirements, autoscaler metrics flow, scaling behavior, and operational verification. ChangesAutoscaling and Observability
Estimated code review effort: 2 (Simple) | ~15 minutes Merge Risk: 🟡 Moderate · up to The documentation currently conflates existing and disabled observability components, which can cause self-hosted users to choose an unsupported configuration and have Helmfile reject the deployment. The PR is not merge-ready until this guidance is corrected or explicitly accepted; the remaining concerns are non-blocking. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Restore the existing observability page structure and examples. Add the self-managed metrics stack details in one focused section and update only statements affected by the new defaults. Signed-off-by: Bora Oztekin <boztekin@nvidia.com>

152-155: 🗄️ Data Integrity & Integration | 🔵 TrivialShow the split deployment in the autoscaler diagram.
The current diagram shows one collector and does not distinguish the compute-plane collection path from the control-plane backend. Show the compute-plane collector remote-writing worker metrics to the backend queried by the control-plane autoscaler.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Document existing and disabled as different modes.
disabled does not mean that another deployment owns a component. For enabled profiles, Helmfile rejects disabled Prometheus Operator CRDs and disabled metrics backends in required paths. Use existing for customer-managed components. Describe disabled only where the selected profile and dependency rules allow the component to be omitted.
Proposed wording
-Profiles set defaults. Components can use `install`, `existing`, or `disabled`
-mode when another deployment owns them.
+Profiles set defaults. Use `existing` when a customer-managed deployment owns a
+component. Use `disabled` only when the selected profile and dependency rules
+permit omitting the component.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

TL;DR
Add self-hosted Function Autoscaler documentation and update the observability guidance for its metrics dependencies.
