Add KEDA solution integration tests following the same pattern as Karpenter. Includes metric existence, instrumentation scope, label decoration, K8s resource attribute, and cloud attribute validation. Changes: - Add test/otel/solutions/keda/ with setup, metrics, and test files - Add SourceKEDA to otelmetrics source registry - Add KEDA Helm install and test ScaledObject to otel terraform - Enable KEDA solution in CloudWatch observability Helm chart - Add keda_version variable (default 2.16.1) - Add KEDA test runner to terraform validator
Update metric definitions based on actual KEDA operator /metrics endpoint: - keda_scaler_errors_total -> keda_scaler_detail_errors_total - keda_resource_totals -> keda_resource_registered_total - Add keda_scaled_object_errors_total - Add keda_trigger_registered_total - Update ExpectedLabels to match actual label names
The actual KEDA metric only exposes 'type' and 'namespace' labels, not 'resource'.
- Add 2-minute wait before KEDA tests for metric propagation in CI - Rename helm_chart_branch to keda_chart_ref variable - Clone helm chart from vaishnavi-30-beep/helm-charts fork - Use path.module for chart path
- Remove all Karpenter-related terraform resources (IAM, helm, nodepool, subnet tags) to make this a KEDA-only branch - Remove karpenter_version variable and Karpenter test runner step - Add ScaledJob workload with cron trigger for keda_scaled_job_errors_total metric coverage - Make cloud.account.id and cloud.resource_id assertions unconditional - Add metric value sanity checks: keda_build_info==1, keda_scaler_active==1, keda_scaler_metrics_value>=0
…all timeout KEDA finalizers deadlock during terraform destroy when the operator pods are removed before ScaledObject/ScaledJob CRs. Add destroy-time provisioners to explicitly delete KEDA custom resources before the helm release is uninstalled.
