feat(telco-kpis): Implement OSLAT test

Add OSLAT (OS Latency) performance test for measuring operating system-induced
latency on Telco-KPIs spoke clusters.

Implements run-oslat-test.yml task with podman-based execution, artifact
collection, and JUnit XML report generation for CI integration.

-# OSLAT test task for Telco-KPIs
-# TODO: Implement actual oslat test logic
-# For now: validates connection and cluster access
+# Run OSLAT latency test
+# Test: OSLAT (OS-level latency test)
+# Purpose: Measure OS latency on isolated CPUs with PerformanceProfile
+# Duration: Configurable via duration parameter (default: 10m)
