Introduce `bgpEnrichment` field in FlowCollector.spec.processor to enable/disable BGP ASN enrichment. When enabled, FLP watches FRRConfiguration resources (frrk8s.metallb.io/v1beta1) and enriches flows with SrcASN/DstASN fields using longest-prefix match against advertised prefixes. Changes: - Add bgpEnrichment bool field to FlowCollectorFLP CRD - Add addBgpEnrichmentStage() in FLP pipeline builder - Add frrk8s.metallb.io/frrconfigurations RBAC for FLP informers - Add kubebuilder RBAC marker for operator to delegate FRR permissions - Add SrcASN/DstASN columns, fields, and filters in console plugin config - Add bgpEnrichment feature flag to console plugin Depends on: netobserv/flowlogs-pipeline#1308 Co-authored-by: Cursor <cursoragent@cursor.com>

📝 WalkthroughWalkthroughThe change adds optional BGP ASN enrichment to FlowCollector. FLP maps flow addresses to ChangesBGP ASN enrichment
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds an optional BGP ASN enrichment feature along with a new end-to-end test. The production code paths (API field, pipeline stage, RBAC, frontend gating) are additive and correctly gated behind an explicit opt-in setting, so existing behavior is unaffected. However, the bundled CRD fixture used as a fallback in the new test is malformed YAML and would fail to apply on clusters lacking the frr-k8s CRD, and the test does not wait for CRD readiness before using it. These should be fixed so the new test is reliable, but they do not affect production behavior. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Wait until the CRD is established.
The GET confirms that the CRD object exists. It does not confirm that the v1beta1 REST endpoint is ready.
If this test installs the CRD, the immediate FRRConfiguration apply can fail before the CRD becomes established. Wait for the Established=True condition before returning.

Restore the generated CRD indentation.
The fixture is not valid YAML. Nested schema content is aligned at the document root, and the multiline description text is not indented.
When the cluster does not contain this CRD, oc apply fails and the BGP enrichment test cannot continue. Replace this file with a correctly generated or copied CRD manifest.

Description
Adds an integration e2e test for BGP ASN enrichment (spec.processor.bgpEnrichment), aligned with existing backend tests (subnet labels, zone enrichment).
The test does not require a live BGP session or frr-k8s operator. It applies a fake FRRConfiguration CR with advertised prefixes and ASN 64512, enables BGP enrichment on FlowCollector, generates traffic with ping pods, and asserts DstASN in Loki for external (8.8.8.8) and internal (192.168.1.0) destinations.
