We can set the container cpuset.cpus diring the creation and it
will not need to call to update resources after the container creation.
Additional side effect of the change, that the runc process that responsible
to create the container will run with the same CPU affinity because the
runc runs on the cpuset provided in the config.json arg.
It will allow to prevent undesirable interupts on isolated CPUs.

If Containerd is used on Windows, then we can also mount individual
files into containers (e.g.: termination-log files), which was not
possible with Docker.
Checks if the container runtime is containerd, and if it is, then also
mount the termination-log file.

The messages for container lifecycle events are subtly inconsistent
and should be unified.
First, the field format for containers is hard to parse for a human,
so include the container name directly in the message for create
and start, and for kill remove the container runtime prefix.
Second, the pulling image event has inconsistent capitalization, fix
that to be sentence without punctuation.
Third, the kill container event was unnecessarily wordy and inconsistent
with the create and start events. Make the following changes:
* Use 'Stopping' instead of 'Killing' since kill is usually reserved for
when we decide to hard stop a container
* Send the event before we dispatch the prestop hook, since this is an
"in-progress" style event vs a "already completed" type event
* Remove the 'cri-o://' / 'docker://' prefix by printing the container
name instead of id (we already do that replacement at the lower level
to prevent high cardinality events)
* Use 'message' instead of 'reason' as the argument name since this is a
string for humans field, not a string for machines field
* Remove the hash values on the container spec changed event because no
human will ever be able to do anything with the hash value
* Use 'Stopping container %s(, explanation)?' form without periods to
follow event conventions
The end result is a more pleasant message for humans:

We've changed the Ephemeral Containers API, and container type will no
longer be required. Since this is the only feature using it, remove it.
This reverts commit ba6f31a6c6.
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
