Support terminal resizing for exec/attach/run
```release-note
Add support for terminal resizing for exec, attach, and run. Note that for Docker, exec sessions
inherit the environment from the primary process, so if the container was created with tty=false,
that means the exec session's TERM variable will default to "dumb". Users can override this by
setting TERM=xterm (or whatever is appropriate) to get the correct "smart" terminal behavior.

Cleanup third party (pt 2)
Move forked-and-hacked golang code to the forked/ directory. Remove ast/build/parse code that is now in stdlib. Remove unused shell2junit
This commit includes a proposal and a Go file to re-define the container
runtime interface.
Note that this is an experimental interface and is expected to go through
multiple revisions once developers start implementing against it. As stated in
the proposal, there are also individual issues to carry discussions of
specific features.
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.
This patch adds the --exit-on-lock-contention flag, which must be used
in conjunction with the --lock-file flag. When provided, it causes the
kubelet to wait for inotify events for that lock file. When an 'open'
event is received, the kubelet will exit.

Remove RunInContainer interface in Kubelet Runtime interface
According to #24689, we should merge RunInContainer and ExecInContainer in the container runtime interface.

WIP v0 NVIDIA GPU support
```release-note
* Alpha support for scheduling pods on machines with NVIDIA GPUs whose kubelets use the `--experimental-nvidia-gpus` flag, using the alpha.kubernetes.io/nvidia-gpu resource
```
Implements part of #24071 for #23587
I am not familiar with the scheduler enough to know what to do with the scores. Mostly punting for now.
Missing items from the implementation plan: limitranger, rkt support, kubectl
support and docs

kubelet: Remove redundant `Container.Created`
As far as I can tell, this has been supplanted by a) the `DockerJSON.CreatedAt` field and b) the
`ContainerStatus.CreatedAt`, where the first is used for creating the
second.
The `.Created` field was only written to as far as I can see.

Is there any reason we might want to keep this around?
This has been supplanted by a) the DockerJSON.CreatedAt field and b) the
ContainerStatus.CreatedAt, where the first is used for creating the
second.
The `.Created` field was only written to as far as I can see.
This is implemented via touching a file on stop as a hook in the systemd
unit. The ctime of this file is then used to get the `finishedAt` time
in the future.
In addition, this changes the `startedAt` and `createdAt` to use the api
server's results rather than the annotations it previously used.
It's possible we might want to move this into the api in the future.
Fixes#23887
Mount hosts' /etc/hosts, /etc/resolv.conf, set host's hostname
when running the pod in the host's network.
Besides, do not set the DNS flags when running in host's network.

Kubelet: Remove nsinit related code and bump up minimum docker apiversion
Docker has native exec support after 1.3.x. We never need this code now.
As for the apiversion, because Kubernetes supports 1.8.x - 1.10.x now, we should bump up the minimum docker apiversion.
@yujuhong I checked the [changes](https://github.com/docker/engine-api/blob/master/types/versions/v1p20/types.go), we are not relying on any of those changes. So #23506 should work with docker 1.8.x+
Add GeneratePodHostNameAndDomain() to RuntimeHelper to
get the hostname of the pod from kubelet.
Also update the logging flag to change the journal match from
_HOSTNAME to _MACHINE_ID.
