Clayton Coleman 3da15535b6 Provide backpressure to clients when etcd goes down ... When etcd is down today we don't specifically handle the error involved, which means clients get a generic 500 error. This commit adds a formal error type internally for both WatchExpired and EtcdUnreachable, and then converts them to api/errors before returning to the client. It also upgrades the client to retry on any 429 or 5xx error that has a Retry-After header, instead of just 429. In combination, this allows the apiserver to exert backpressure on controllers that are hotlooping. Picked 2 seconds by default, but we could potentially ramp that up even further in a future iteration.		2015-11-04 16:05:12 -05:00
