Rewrite Grok Debugger Tests to use Standard Functional Test Runner (#…

…108301)

* Converted Grok debugger tests to use standard functional test runner practices.

* Fixed last test.

* Removed old test now that the new test is passing.

* Fixed condition for retry.

* Removed .only to restore test run.

* fixed errors

* Fixed nits.
