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.
