Yu-Ju Hong ff04de4fc0 Remove RuntimeCache from sync path 
This change removes RuntimeCache in the pod workers and the syncPod() function.
Note that it doesn't deprecate RuntimeCache completely as other components
still rely on the cache.

Ken Robertson a7b07c01df Update container runtime to properly report the engine and version 
This address a TODO when collecting the node version information so it
will properly report the configured runtime and its version. Previously,
this was hardcoded to "docker://" and the docker version, and would show
"docker://1.9.1" even when the kubelet was configured to use rkt.

With this change, it will use the runtime's Type() and Version() data.

This also changes the container.Runtime interface to add an APIVersion()
method. This can be used when the runtime has separate versions for the
engine and the API, such as with Docker. The Docker minimum version
validation has been updated to use APIVersion(), and
DockerManager.Version() now returns the engine version.

Yu-Ju Hong 032c0a4074 Add container.Cache for storing container.PodStatus 
This cache will be used to stores the PodStatus of all pods/containers
visible on the node. This will elimiate the need for pod workers to query the
container runtime directly.

Yu-Ju Hong 73a4f8225c PLEG should report events if a container is removed 
Currently, pleg would report a event if a container transitions from running to
exited between relisting. However, if would not report any event if a container
gets stopped and removed between relisting. This event will eventually be
handled when the pod syncs periodically, but this is undesirable. This change
ensures that we detect all such events.

Tim St. Clair 89bc7992f9 Refactor kubelet server into its own package 
Refactor Kubelet's server functionality into a server package. Most
notably, move pkg/kubelet/server.go into
pkg/kubelet/server/server.go. This will lead to better separation of
concerns and a more readable code hierarchy.

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.

Yu-Ju Hong bc6414a873 kubelet: add a generic pod lifecycle event generator 
This change introduces pod lifecycle event generator (PLEG), and adds a generic
PLEG. The generic PLEG relies on relisting to discover container events, and is
container-runtime-agnostic. Both docker and rkt are changed to use generic
PLEG.
