There is a JVM bug causing `Thread#suspend` calls to randomly take multiple seconds breaking these tests that call the method numerous times in a loop. Increasing the timeout would will not work since we may call `suspend` tens if not hundreds of times and even a small number of them experiencing the blocking will lead to multiple minutes of waiting. This PR detects the specific issue by timing the `Thread#suspend` calls and skips the remainder of the test if it timed out because of the JVM bug. Closes elastic#50047
