Use the generic runtime method to get the netns path. Also
move reading the container IP address into cni (based off kubenet)
instead of having it in the Docker manager code. Both old and new
methods use nsenter and /sbin/ip and should be functionally
equivalent.

Sets IgnoreUnknown=1 in CNI_ARGS
```release-note
release-note-none
```
K8 uses CNI_ARGS to pass pod namespace, name and infra container
id to the CNI network plugin. CNI logic will throw an error
if these args are not known to it, unless the user specifies
IgnoreUnknown as part of CNI_ARGS. This PR sets IgnoreUnknown=1
to prevent the CNI logic from erroring and blocking pod setup.

This commit builds on previous work and creates an independent
worker for every liveness probe. Liveness probes behave largely the same
as readiness probes, so much of the code is shared by introducing a
probeType paramater to distinguish the type when it matters. The
circular dependency between the runtime and the prober is broken by
exposing a shared liveness ResultsManager, owned by the
kubelet. Finally, an Updates channel is introduced to the ResultsManager
so the kubelet can react to unhealthy containers immediately.
Change all references to the container ID in pkg/kubelet/... to the
strong type defined in pkg/kubelet/container: ContainerID
The motivation for this change is to make the format of the ID
unambiguous, specifically whether or not it includes the runtime
prefix (e.g. "docker://").
Each container with a readiness has an individual go-routine which
handles periodic probing for that container. The results are cached, and
written to the status.Manager in the pod sync path.
Add an experimental network plugin implementation named "cni" that
uses the Container Networking Interface (CNI) specification for
configuring networking for pods.
