Reduce reaper poll interval and wait while resizing

When reaping a replication controller that handles an arbitrary amount of replicas, missing an interval means that `kubectl stop|delete` have to wait 3 more seconds to finish which seems more expensive from a user pov than a GET per 100ms.

Also I think `kubectl resize` should wait for all replicas to spin up before exiting. Feels more safe to know that your replication controller status is up to date.
