bf170a688c Update annotations in the kubelet. 
When the pod annotations are updated in the apiserver, update the pod.
Annotations may be used to convey attributes that are required to the
pod execution, such as networking parameters.

ccd0fcd1f9 Rmove Hostname health check 
The health check is no longer needed since health checks are no longer
run by master but updated by the kubelet; so a host with the incorrect
host name will not be updated and show 'NotReady' status

8774f6efa2 kubelet: don't remove any pod directory with non-empty volumes 
If the volumes directory is not empty, it implies that volumes may not have
been properly cleaned up yet. Do not attempt to remove the pod directory.

697197d383 Kubelet: do not remove pod directory if any container is still running 
If there are any running container in the pod, we cannot remove the volume.
Therefore, we should not attempt to remove the pod directory.

Allow the user to specify the resolver configuration file that is used
to determine the default DNS parameters. This defaults to the system's

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.

80e799fc0c Allow configuring the rkt binary in a kubelet with a flag. 
This is necessary because coreos comes with rkt installed, and if we want to use a different version
we need some way to avoid the default one.
