test(bdd): cover all observability profile

[sbaum1994]

TL;DR

Adds the final live observability-profile BDD scenario. It installs the complete control and compute stack on one ncp-local cluster and proves both planes share one observability stack.

Additional Details

• Adds table-driven fake-runner wiring coverage for the new feature.
• Verifies revision-1 shared releases, Target Allocator, control and compute monitors, healthy NVCA, and the NVCA self-managed collector.
• Removes an unsupported optional router algorithm from the shared local fixture. The pinned router chart still uses an older Stargate image that cannot parse that algorithm.
• Customer release notes: Not customer visible.
• Plan summary: Test-only coverage; no deployed resource defaults change.
• Usage: Run go test -run '^TestObservabilityAll$' -count=1 -v -timeout 60m from tests/bdd with the documented live-test environment.
• Dependencies: None. License and NOTICE files are unchanged.
• Related pull request: fix(compute-plane): update observability defaults and coverage #648.

For the Reviewer

Please focus on the one-stack revision assertions and the combined control/compute monitor set in observability-all.feature.

For QA

• cd tests/bdd && go test -short ./...
• cd tests/bdd && ./scripts/lint.sh
• Fresh destructive ncp-local run: 1 scenario and 45 steps passed in 16m50s.
• No additional QA is needed.

Issues

Closes #522

Summary by CodeRabbit

• Tests
  • Added end-to-end coverage for installing the complete observability profile across self-managed control and compute planes.

📝 Walkthrough

Walkthrough

Adds BDD coverage for installing and validating the all observability profile on one local cluster. Adds fake-runner and live test wiring, topology and command-safety checks, credential injection, and observability resource assertions.

Changes

All observability profile

Layer / File(s)	Summary
Profile setup and topology prerequisites tests/bdd/features/observability-all.feature, tests/bdd/fixtures/self-managed-local-bdd.yaml	Defines shared Helmfile environments, image and credential settings, isolated kubeconfig checks, topology conflict checks, and pull-secret validation. Removes the wait-and-widen load-balancer algorithm.
Stack installation and credential injection tests/bdd/features/observability-all.feature	Installs the self-managed stack, registers the local compute cluster, installs the compute plane, and injects the NGC credential into the NVCA namespace.
Observability validation and test wiring tests/bdd/features/observability-all.feature, tests/bdd/godog_test.go	Checks Helm revisions, NVCA rollout and backend health, target allocation, monitors, and collector settings. Adds fake-runner assertions, Helm release fixtures, and a live test entry point.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 17eb9

This PR adds live observability-profile coverage but does not assert the required BYOObservability feature gate, leaving the profile contract incompletely tested. Merge should wait until that assertion is added or the omission is explicitly accepted.

In `@tests/bdd/features/observability-all.feature`:
- Around line 136-141: Update the observability feature scenario to query
.selfManaged.featureGateValues[] and assert the output contains
"BYOObservability" instead of checking the OTEL collector setting. Add the
corresponding fake-runner command and expected output handling in godog_test.go,
reusing the existing command-matching patterns.
- Around line 125-134: Update tests/bdd/PLAN.md to document the context-specific
image pull secret step used by observability-all.feature, including its using
context variant, alongside the existing image pull secret step entry. Do not add
a handler or modify the feature scenario.
- Around line 46-49: Update the conflict-precheck instructions in
observability-all.feature to use the targeted make destroy command with
CLUSTER_NAME=ncp-local-cp, replacing destroy-all-ncp-local while preserving the
surrounding retry guidance.
