fix: support serverless logs and robust timeout in diagnose scripts

[Ayush-Patel-56]

Ⅰ. Describe what this PR does

Updates diagnostic scripts across all runtimes to support serverless mode and improve macOS compatibility.

Changes:

• Added log collection for Fuse sidecars in pods labeled serverless.fluid.io/inject=true.
• Updated the run helper to use gtimeout or perl as a fallback when GNU timeout is missing.
• Fixed a variable typo (fluid_namesapce) in the GooseFS script.

Ⅱ. Does this pull request fix one issue?

fixes #1852

Ⅲ. List the added test cases (unit test/integration test) if any, please explain if no tests are needed.

Manual verification of the timeout logic on systems without GNU coreutils. No tests needed for these standalone shell utilities.

Ⅳ. Describe how to verify it

1. Run any diagnostic script on macOS; it should now use the perl fallback instead of failing with command not found.
2. Run in a namespace with serverless workloads to verify sidecar logs are captured in the tarball.

Ⅴ. Special notes for reviews

Used a perl one-liner for the timeout fallback to keep the scripts dependency-free.

Hi @Ayush-Patel-56. Thanks for your PR.

I'm waiting for a fluid-cloudnative member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Summary of Changes

Hello @Ayush-Patel-56, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the diagnostic scripts for Fluid runtimes by introducing support for collecting logs from serverless-enabled pods and improving the robustness of command timeouts. These changes ensure that diagnostic information can be gathered more comprehensively across different deployment environments and operating systems, particularly macOS, by providing alternative timeout mechanisms.

Highlights

• Serverless Log Collection: Added functionality to collect logs from fluid-fuse sidecar containers in serverless-labeled pods across all diagnostic scripts.
• Robust Timeout Mechanism: Implemented fallbacks for the timeout command, using gtimeout or a perl one-liner, to improve compatibility, especially on macOS.
• GooseFS Script Fix: Corrected a variable typo (fluid_namesapce to fluid_namespace) and improved string comparison in the GooseFS diagnostic script.

Code Review

This pull request enhances the diagnostic scripts by adding support for serverless logs and improving timeout handling, particularly for macOS compatibility. The changes involve modifying the run function to use gtimeout or perl as fallbacks for timeout, adding a serverless_pod_logs function to collect logs from serverless pods, and incorporating this function into the pd_collect function in multiple shell scripts. Additionally, a typo in the GooseFS script has been fixed.

Pull request overview

This PR updates the runtime-specific diagnostic shell scripts to better support serverless (sidecar-injected) workloads and improve compatibility on macOS systems that lack GNU timeout.

Changes:

• Adds serverless pod fuse-sidecar log collection for pods labeled serverless.fluid.io/inject=true.
• Fixes a namespace variable typo/bug in the GooseFS diagnose script.
