augmentcode[bot]andlnx01 3a77f487da test: migrate cpu_hog functional test to tests_v2 (closes #1390) (#1391)
* test: migrate cpu_hog functional test to tests_v2 (closes #1390)

Migrate the legacy CI/tests/test_cpu_hog.sh to the v2 pytest framework
under CI/tests_v2/scenarios/cpu_hog/, preserving parity with the legacy
flow and adding stronger functional and negative coverage.

- Add scenario_base.yaml (flat hog_scenarios config, patched per test)
- Add test_cpu_hog.py with TestCpuHog(BaseScenarioTest):
  - success: hog pod created on node-selector target, run exits 0, pod cleaned up
  - negative: node-selector matching zero nodes fails gracefully
  - negative: missing mandatory hog-type fails at config parsing
- Register cpu_hog marker in pytest.ini
- Document cpu_hog coverage in README.md

* test: kill background Kraken proc on any cpu_hog success-test failure

Broaden the success-path teardown so a poll/assert failure before
proc.communicate() also kills the background Kraken process, preventing
a lingering cpu-hog- pod from stressing the node and racing --reruns.

Addresses Deep Code Review feedback on PR #1391.
