Raoul Scarazzini 9eb8afa547 Fix instance test to check for running status
This commit removes the arbitrary sleep of 5 seconds and look instead
for the instance status to become "Running". If after the timeout the
status is not reached then a failure is injected.
This will fix slow environments in which 5 seconds weren't enough for an
instance to come up properly.
