Because unavailability timer resets every time the controller leader changes, robustly waiting for the timer to elapse is hard. Instead we simply wait until the unavailable node appears in the "violations" status field. (cherry picked from commit ce4a809)

Previously, when the controller leader node was suspended during the test all status requests would fail with the timed-out error. This was true for all nodes, not just the suspended one (because we proxy the status request to the controller leader), so internal retries in the admin API wrapper didn't help. We increase the timeout and add 504 to retriable status codes so that internal retries can handle this situation. (cherry picked from commit dc83a7b)
