a2dac158c2 kubelet/container: Remove ipcMode and netMode from RunContainerOptions. 
Since createPodInfraContainer() is moved into dockertools. There is no
need to pass the ipcMode or netMode via RunContainerOptions.

2cf0dfb79d Handle out of disk situation on kubelets. 
Kubelet will stop accepting new pods if it detects low disk space on root fs or fs holding docker images.
Running pods are not affected. low-diskspace-threshold-mb is used to configure the low diskspace threshold.

7831b7da72 kubelet/container: Move prober.ContainerCommandRunner to container. 
Also include the ContainerCommandRunner in Runtime interface, but
still keep the ContainerCommandRunner interface for testability.

d231eb6bef Kubelet: wait until container runtime is up

runtime to be up.

79fc8bee34 Change GetContainerLogs() signature. 
This works for both runtimes. We need to eventually unify the ID scheme
for this method.

1ad4dd7803 Kubelet: replace DockerManager with the Runtime interface 
This change instructs kubelet to switch to using the Runtime interface. In order
to do it, the change moves the Prober instantiation to DockerManager.

Note that most of the tests in kubelet_test.go needs to be migrated to
dockertools. For now, we use type assertion to convert the Runtime interface to
DockerManager in most tests.

Kubernetes Authors", which is generic.

3b9eba2c1b Add SyncPod() to DockerManager and use in Kubelet. 
This allows us to abstract away the logic of syncing a pod by the
runtime. It will allow other runtimes to perform their own sync as well.

83c599e4d4 Add image-related methods to DockerManager 
This change is part of the efforts to make DockerManager implement the Runtime
interface.

The change also modifies the interface slightly to work with existing
code, and aggregates the type converting functions to convert.go.

d81ecc58f8 Adapt pod killing and cleanup for generic container runtime 
This change removes docker-specifc code in killUnwantedPods. It
also instructs the cleanup code to move away from interacting with
containers directly. They should always deal with the pod-level
abstraction if at all possible.
