Yu-Ju Hong c8a075ad62 Do not delete pod status entry when apiserver returns NotFound error 
The logic doesn't apply to static pods as their corresponding mirror pod may
not have been created yet, or may be in the process of recreation. Deleting the
pod status immediately resets the version of the status for the static pod,
while the apiStatusVersion remains unchanged. This could lead to incorrect
versioning and hence stale pod status in the apiserver.

Yu-Ju Hong a4816b3bcb Make kublet/util/format.go a separate package 
The formatting function is used often in logging. This improves the readability
by shortening the length of the call. Also change the fomartted string to
include the pod UID.

Tim Hockin e6df0b1a24 Convert validation to use FieldPath 
Before this change we have a mish-mash of ways to pass field names around for
error generation.  Sometimes string fieldnames, sometimes .Prefix(), sometimes
neither, often wrong names or not indexed when it should be.

Instead of that mess, this is part one of a couple of commits that will make it
more strongly typed and hopefully encourage correct behavior.  At least you
will have to think about field names, which is better than nothing.

It turned out to be really hard to do this incrementally.

Jan Chaloupka 9590b23264 LowThresholdPercent can not be higher than HighThresholdPercent 
if LowThresholdPercent > HighThresholdPercent, amountToFree at image_manager.go:208 is negative and image GC will not free memory properly.

Justification:

1) LowThresholdPercent > HighThresholdPercent implies (LowThresholdPercent * capacity / 100) > (HighThresholdPercent * capacity / 100)
2) usage is at least (HighThresholdPercent * capacity / 100)
3) amountToFree = usage - (LowThresholdPercent * capacity / 100)

Combining 1), 2) and 3) implies amountToFree can be negative.

What happens if amountToFree is negative? in freeSpace method, "for _, image := range images " loops at least once
and if everything goes fine, "delete(im.imageRecords, image.id)" is executed.
When checking for condition "if spaceFreed >= bytesToFree", it is always true as bytesToFree is negative
and spaceFreed is positive. The loop is finished, so is image GC.

At the end, only the oldest image is deleted. In situations where there is a lot of dead containers,
each container corresponing to distinct image, number of unused images can get higher.
If two new images get pulled in every 5 minutes, image GC will not work properly and will not free enough space.
Secondly, it will take a lot of time to free all unused images (hours depending on a number of unused images).

This is an incorrect configuration. Image GC should report it and refuse to work.

Yu-Ju Hong dc42d25f4a kubelet: remove background updating thread in RuntimeCache 
This feature is no longer useful pods don't sync as often. For batch
creation/deletions/syncs, the cache will be up-to-date for most pods since it
will be updated frequently. For other cases, continue updating for two more
seconds don't usually help, as temporal locality doesn't hold across pod syncs.

10 second in this case.

Yu-Ju Hong bc6414a873 kubelet: add a generic pod lifecycle event generator

PLEG.

kargakis d519741e1b kubelet: Fallback to api server for pod status 
This commit fixes getting the logs from complete/failed pods after
a kubelet restart by falling back to the api server in case we fail
to resolve the pod status using the status cache.

Tim St. Clair 1e88a682da Add liveness/readiness probe parameters 
- PeriodSeconds - How often to probe
- SuccessThreshold - Number of successful probes to go from failure to success state
- FailureThreshold - Number of failing probes to go from success to failure state

This commit includes to changes in behavior:

1. InitialDelaySeconds now defaults to 10 seconds, rather than the
kubelet sync interval (although that also defaults to 10 seconds).
2. Prober only retries on probe error, not failure. To compensate, the
default FailureThreshold is set to the maxRetries, 3.

Justin Santa Barbara b2c2d617cf Label nodes with Zone information, if available 
This lays the groundwork for simple multizone capabilities.

In a cloud environment, nodes are typically created by the kubelet
registering with the API server.  When creating a new node, we now query
the cloudprovider to see if it can provide Zone information, and if so
we add some well-known labels to the Node we are creating.

Yu-Ju Hong 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.
