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.

858126b42a Clean up static/mirror pod status logic 
- status.Manager always deals with the local (static) pod, but gets the
  mirror pod when syncing
  - This lets components like the probe workers ignore mirror pods

b734155954 Clean up housekeeping routine in kubelet 
Now that kubelet checks sources seen correctly, there is no need to enforce the
initial order of pod updates and housekeeping. Use a ticker for housekeeping to
simplify the code.

2eb17df46b kubelet: independent pod syncs and backoff on error 
Currently kubelet syncs all pods every 10s. This is not preferred because
 * Some pods may have been sync'd recently.
 * This may cause all the pods to be sync'd at once, causing undesirable
   CPU spikes.

This PR replaces the global syncs with independent, periodic pod syncs. At the
end of syncing, each pod worker will enqueue itslef with a future timestamp (
current time + sync interval), when it will be due for another sync.
 * If the pod worker encoutners an sync error, it may requeue with a different
   timestamp to retry sooner.
 * If a sync is triggered by the update channel (events or spec changes), the
   pod worker would enqueue a new sync time.

This change is necessary for moving to long or no periodic sync period once pod
lifecycle event generator is completed. We will still rely on the mechanism to
requeue the pod on sync error.

This change also makes sure that if a sync does not succeed (either due to
real error or the per-container backoff mechanism), an error would be propagated
back to the pod worker, which is responsible for requeuing.
