What type of PR is this?
Feature
What this PR does / why we need it:
Adds the complete nkp-etcd-maintenance enterprise suite to the staging directory for catalog publication. Features include:
Defragmentation: Leader-safe, cluster-wide CronJob.
Snapshots: 3-stage emptyDir Pod pipeline with optional S3 upload.
Observability: 8 capability-gated PromQL alerts for etcd health and job monitoring.
Quota Bumper: Stateless orchestrator script for emergency 8GB quota expansion.
Docs: Comprehensive README.md with a strict Manual Restore Runbook.
Key files to review (by priority):
To respect your time, please focus on these critical paths:
Tier 1 (Security & Core Logic - Must Read):
templates/-cronjob.yaml: Check emptyDir usage, read-only mounts, and init-container ordering.
templates/rbac.yaml & templates/quota-bumper/rbac.yaml: Ensure least-privilege scoping.
files/quota-bumper/patch-manifest.sh & scripts/quota-bumper/orchestrator.sh: Review atomic mv, idempotency, and shrink-refusal safety gates.
files/quota-bumper/verify-restart.sh: Mitigates the "Ghost Health Check" to ensure the orchestrator doesn't proceed while a node is unhealthy.
Tier 2 (Operator UX & Configuration):
values.yaml: Operator-facing contract, defaults, and fail-fast invariants.
templates/prometheusrule.yaml: PromQL math and capability gating.
Context Only (Skim):
README.md, COMMANDS.md, LLD-.md, and misc boilerplate.
Which issue(s) this PR fixes:
Fixes NCN-114550, NCN-114552
Special notes for your reviewer:
End-to-end validated on a live 3-control-plane NKP cluster.
Post-merge, I will run the Publish Chart to GHCR workflow on the catalog repo to finalize the mirroring.
