OSAC-4435: harden BMaaS e2e test error handling and isolation checks

[jira-autofix]

Summary

Addresses five automated review findings from PR #488 on BMaaS e2e test files.

Changes

• Network isolation false-positive prevention (test_bmaas_networking.py): Added SSH transport verification (ssh_bmi(host, "true")) before negative connectivity assertions in test_09_l2_arping_cross_subnet_fails and test_10_tenant_isolation. Previously, if SSH transport itself failed, the non-zero return code was interpreted as "no connectivity", causing the isolation tests to falsely pass.

• TimeoutExpired handling (test_bmaas_networking.py): Added subprocess.TimeoutExpired to the except clause in _try_ssh_eip within test_12_external_ip_ingress. TimeoutExpired is not a subclass of CalledProcessError, so an SSH timeout would propagate as an unhandled exception instead of being retried.

• Resilient cleanup loop (test_baremetal_instance_inventory_exhausted.py): Wrapped individual _cleanup_bmi calls in the finally block with try/except so that one failed cleanup no longer aborts the remaining cleanups, preventing BMI inventory leaks.

• Cleanup error logging (test_baremetal_instance_lifecycle.py): Replaced bare pass in the cleanup exception handler with logger.exception() so cleanup failures leave a log trace for debugging.

Not changed

• Finding 3 (pytest-xdist parallel execution concern) is already addressed by the test's placement in serial/ directory with pytestmark = pytest.mark.serial.
• Netris workflow hardening items from Jira comments are in osac-test-infra, not this repository.

Summary

• Tests: Hardened BMaaS end-to-end tests with SSH validation, retry handling, and resilient BMI cleanup.
• Other areas: No API, controller, database, auth, deployment, CI, or documentation changes identified.
• Compatibility: No backward-compatibility impact is expected.
• Testing status: Test execution results were not provided.

Risk classification

risk:ship applies because the changes are limited to test code and do not alter production behavior. risk:show does not apply because there is no user-visible product change. risk:ask does not apply because no higher-risk behavior or unresolved production impact was identified.

Walkthrough

The BMaaS end-to-end tests now validate SSH transport before negative network assertions. External-IP SSH retries include timeout failures. Cleanup paths log failures, continue processing instances, and report accumulated errors.

Changes

BMaaS test reliability

Layer / File(s)	Summary
Networking validation and retries tests/e2e/bmaas/regression/networking/test_bmaas_networking.py	The tests verify successful SSH transport before cross-subnet ARP and tenant-isolation assertions. External-IP SSH retries also handle subprocess.TimeoutExpired.
Cleanup failure handling tests/e2e/bmaas/serial/test_baremetal_instance_inventory_exhausted.py, tests/e2e/bmaas/sanity/test_baremetal_instance_lifecycle.py	Cleanup failures are logged with BMI identifiers. Inventory cleanup processes every BMI, then raises a RuntimeError with the first failure chained as its cause.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 7f9f9

When provisioning or an assertion fails and cleanup also fails, the reported failure can focus on cleanup rather than the original test failure. Preserve both failure causes before merging so BMaaS test failures remain diagnosable.

Full details: No-Sensitive-Data-In-Logs

Explanation

The pull request adds logger.exception(...) calls that can log bearer tokens. GRPCClient._build_args() places the live token in the Authorization: Bearer ... command argument. subprocess.CalledProcessError.__str__() includes the command arguments. Cleanup calls wait_for_bmi_grpc_removal(), which calls the gRPC client, and the new exception handlers log the full traceback when that call fails. The BMaaS fixture supplies real JWT or service-account tokens. The previous code did not log these cleanup exceptions. This introduces token exposure in logs.

Resolution

Redact credentials before logging cleanup failures. Do not pass raw CalledProcessError objects to logger.exception() when their command can contain an Authorization header. Sanitize command arguments and exception output, or change the gRPC runner to remove the bearer token from exception representations, then log only the sanitized error and BMI identifier.
