RFR(s): 8168409 Update list of tools run by the jtreg timeouthandler

[Staffan Larsen]

Dmitry,

I would like to avoid running SA-based tools in the timeout handler since on macOS they pop up dialogs asking for permission to attach to the process. This is problematic in our testing infrastructure. Instead, I hope we can run jhsdb on the core file that is generated.

I tried doing this automatically in the timeout handler, but could not find a simple way to do it. jhsdb requires the path to the executable and the timeout handler does not know this. Perhaps a future enhancement to the timeout handler could fix this.

This change removes all calls to the old SA-tools and instead uses Diagnostic Commands to gather the same information. The possible drawback is that Diagnostic Commands do not work on processes where the JVM is completely hung, but in that case we can fallback to running the SA-tools on the core file that is also generated.
