Remove benchmark-operator references, rename templates, and remove kata workloads

[arpsharm]

Type of change

• enhancement

Description

All workloads (stressng, uperf, hammerdb) have been migrated to native Kubernetes. This PR removes all dead benchmark-operator code, renames template files to clean conventions, removes kata workloads, renames PIN_NODE_BENCHMARK_OPERATOR to PIN_NODE0, and fixes the oc.py grep→jsonpath issue for pod/VMI detection.

Deleted

• benchmark_runner/benchmark_operator/ directory (entire operator code path)
• Old ripsaw CRD templates (stressng_pod/vm, uperf_pod/vm)
• Operator test files and docs (build_fedora_benchmark_operator.md)
• All kata golden test files

Edited

• main.py — removed operator routing and imports
• environment_variables.py — removed kata workloads, changed fallback namespace to benchmark-runner, namespace resolution reorder (dict first, NAMESPACE fallback)
• template_operations.py — skip standard template if file doesn't exist
• oc.py — replaced -o name | grep with -o jsonpath for both pod and VMI detection, removed operator comments
• Dockerfiles, CI workflows — removed operator version/clone steps
• Renamed stressng_pod_job_template → stressng_pod_template, stressng_vm_direct_template → stressng_vm_template, uperf_vm_direct_template → uperf_vm_template
• Renamed PIN_NODE_BENCHMARK_OPERATOR → PIN_NODE0 across all files (env vars, CI workflows, docs, ES metadata)
• Updated develop.md and HOW_TO.md — removed operator sections, updated examples
• Added ES integration test for native workloads (test_elasticsearch_operations_workloads.py)

Did you update allso the readme files ?

[ebattat]

we should have elasticsearch test w/o benchmark-runner.
Can we have the same test but using benchmark-runner uperf pod ?

You should replace:
self._environment_variables_dict['pin_node_benchmark_operator'] = EnvironmentVariables.get_env('PIN_NODE_BENCHMARK_OPERATOR', '')
by:
self._environment_variables_dict['pin_node0'] = EnvironmentVariables.get_env('PIN_NODE0, '')
