[release][ci] First test for kuberay release test trigger path

[khluu]

• Modify Kuberay release test trigger code to catch exception and store it in Result
• Modify glue unit test to include Kuberay variant of the release test trigger path

[Copilot]

Pull Request Overview

This PR extends the release test framework to support a KubeRay variant and updates unit tests accordingly.

• Test changes to initialize a KubeRay compute config and exercise the new kuberay flag in error scenarios.
• Glue code adds exception capture in the KubeRay path, records runtime, and maps exceptions to Result.

File	Description
release/ray_release/tests/test_glue.py	Set up self.kuberay_test, extend _run to take a kuberay flag, and duplicate error-path tests for KubeRay.
release/ray_release/glue.py	Wrap KubeRay execution in try/except, record start_time/runtime, call handle_exception, and rethrow.

• [nitpick] All error paths for KubeRay are covered, but there is no test for a successful KubeRay run. Consider adding a positive test to verify that self._run(result, True) sets return_code == 0 and populates expected fields.

        self.assertEqual(result.return_code, ExitCode.CONFIG_ERROR.value)

release/ray_release/tests/test_glue.py:259

• [nitpick] The parameter name kuberay is a bit ambiguous as a flag. Consider renaming to something like use_kuberay or is_kuberay for clarity.

    def _run(self, result: Result, kuberay: bool = False, **kwargs):

release/ray_release/tests/test_glue.py:317

• This assertion is indented inside the with self.assertRaisesRegex(...) block, so it never runs after the exception is raised. Move it outside the with at the same indentation level to ensure it's executed.

        self.assertEqual(result.return_code, ExitCode.CONFIG_ERROR.value)

this wrapping does not really feel right.. to start, catching all Exception is not the right thing to do in most cases. could you explain what exactly you are trying to do?

[khluu]

I'm using try/catch here mostly to retain the Exception that can be thrown any time commands run inside try. run_release_test_anyscale also implements the same thing. The purpose (I think) is to throw the right error code that matches with whatever errored out during the process (thus why it needs to retain the right exception msg)
