78ce5da988 Move util.StringSet into its own package 
A lot of packages use StringSet, but they don't use anything else from
the util package. Moving StringSet into another package will shrink
their dependency trees significantly.

9a5f43e16d Kubelet#GetNode now uses GetNodeInfo instead of List 
Both GetNode and the cache.ListWatch listfunc in the
kubelet package call List unnecessary.

GetNodeInfo is sufficient for GetNode and makes looping
through a list of nodes to check for a matching name
unnecessary.

08ec796995 kubelet: remove orphaned pod directories properly 
PR #13293 added a safety check to not remove a pod directory if the child
volumes directory is not empty. This logic is faulty because kubelet may have
directory structures podUID/volumes/volumeKind/volumeName. E.g.,
`056db95d-50ee-11e5-a2e4-42010af0ba1d/volumes/kubernetes.io~empty-dir/default-token-al3r2`

This change fixes that by properly listing all volumes under a pod.

13b268b378 kubelet: define the minimum housekeeping period 
Before, kubelet performs global cleanup tasks every iteration. After the
PR #13003, kubelet performs the tasks on every sync internval (10 seconds).
This PR decouples the housekeeping period with the sync internval to ensure
that kubelet cleans up promptly, while not too often (no more than once every
minimum housekeeping period).

b906e34576 kubelet: trigger pod workers independently 
Currently, whenever there is any update, kubelet would force all pod workers to
sync again, causing resource contention and hence performance degradation.

This commit flips kubelet to use incremental updates (as opposed to snapshots).
This allows us to know what pods have changed and send updates to those pod
workers only. The `SyncPods` function has been replaced with individual
handlers, each handling an operation (ADD, REMOVE, UPDATE). Pod workers are
still triggered periodically, and kubelet performs periodic cleanup as well.

This commit also spawns a new goroutine solely responsible for killing pods.
This is necessary because pod killing could hold up the sync loop for
indefinitely long amount of time now user can define the graceful termination
period in the container spec.

0c84b837cf kubelet: switch to using pod UID as the key in status manager 
We chose to use podFullName (name_namespace) as key in the status manager
because mirror pod and static pod share the same status. This is no longer
needed because we do not store statuses for static pods anymore (we only
store statuses for their mirror pods). Also, reviously, a few fixes were
merged to ensure statuses are cleaned up so that a new pod with the same
name would not resuse an old status.

This change cleans up the code by using UID as key so that the code would
become less brittle.

780accb3ba Kubelet should garbage collect dead pods 
The sync loop should check for terminated pods that are no longer
running and clear them. The status loop should never write status
if the pod UID changes. Mirror pods should be deleted immediately
rather than gracefully.

89f1f3b1b8 Alter graceful deletion to not use TTL 
Avoid TTL by deleting pods immediately when they aren't
scheduled, and letting the Kubelet delete them otherwise.

Ensure the Kubelet uses pod.Spec.TerminationGracePeriodSeconds
when no pod.DeletionGracePeriodSeconds is available.

01f3785426 Add status.podIP as a valid downward API target 
Getting the public IP a container is supposed to use is O(hard),
and usually involves ugly gyrations in python or with interfaces.
Using the downward API means that the IP Kube is announcing to
other endpoints is also visible inside the container for pods to
identify themselves.

56f4605f47 kubelet: refactor SyncPods for better readability 
Eventually we would like to replace the all-encompassing SyncPods function with
more well-defined, smaller functions. This would not only help with the
readability and profiling of the code, it'd also set in motion for the plans to
trigger pod worker individually based on the content of the pod updates.

This commit serves as the first step of that, while avoiding breaking all unit
tests by preserving the SyncPods function for the time being.
