Fix Prometheus queries using correct OpenShift metrics from console dashboard

Browse Source 
- Updated CPU usage query to use node_namespace_pod_container:container_cpu_usage_seconds_total:sum_irate
- Updated memory usage query to use container_memory_working_set_bytes with correct job and metrics_path
- Updated requests/limits queries to use kube_resourcequota with correct cluster and type parameters
- Applied fixes to both get_workload_historical_analysis and get_namespace_historical_analysis functions
- Queries now match the working queries from OpenShift console dashboard
