Fix duplicate comment in iptables rule for non-local public-port rule
**What this PR does / why we need it**:
When kubernetes creates an iptable rule for "from-non-local public-port"
rule the rule gets created with two identical comment section.
The function `iptablesNonLocalNodePortArgs` creates a list of arguments
for the rule from iptablesCommonPortalArgs function. This function
already appends the arguments for the rules comments and therefore does
not require appending the comment again.
**Special notes for your reviewer**:
I'm actually not a go programmer at all and have no idea how your tests work.
I doubt that my fix will require adjustements on tests but I'm not 100% sure.
If additional work is needed, I would be glad if someone could point it out to me so I can take care of it.

Fix a bug that headless service without ports fails to have endpoint created.
**What this PR does / why we need it**:
Follow up of https://github.com/kubernetes/kubernetes/pull/47250. Headless service without ports fails to have corresponding endpoint created because endpoint controller deliberately attaches a dummy endpointPort with portNum=0, which will fail API validation check. Error as below:
```
endpoints_controller.go:375] Error syncing endpoints for service "default/XXX": Endpoints "XXX" is invalid: subsets[0].ports[0].port: Invalid value: 0: must be between 1 and 65535, inclusive
```
This PR makes endpoint controller not attach the dummy endpointPort for headless service.

Move pkg/scheduler/util/testutil.go to pkg/scheduler/testing
**What this PR does / why we need it**:
In the package `k8s.io/kubernetes/pkg/scheduler/util`, we have testutil.go, which has an init() function. Since this package is imported in production code, we are inadvertently running test code in production.
Fortunately (depending on how you look at it) scheduler already has a package called `k8s.io/kubernetes/pkg/scheduler/testing` which would be an appropriate home for these utils.

Support containerized kubelet in CI
**What this PR does / why we need it**:
* Adjust hyperkube Makefile to allow HYPERKUBE_BIN to be
specified from outside
* new DOCKER_ROOT variable to specify --root-dir and associated
volume for kubelet to know where docker directory lives
* Save the docker logs when we kill the kubelet container
* Allow customized image for dockerized kubelet and build a Default
image if one is not specified
We should allow a custom build using script we have:
`VERSION="latest" REGISTRY="k8s.gcr.io" hack/dev-push-hyperkube.sh`
to be used quickly using DOCKERIZE_KUBELET. To do this we remove the
hard coded `k8s.gcr.io/kubelet` image and introduce a new environment
variable `KUBELET_IMAGE`.
Note that we are switching to hyperkube from kubelet as we have a quick
and easy script to build hyperkube image and load it into local docker
daemon. This reduces bad hacks like `docker tag
k8s.gcr.io/hyperkube-amd64:<tag> k8s.gcr.io/kubelet:latest` being used
by folks today (see 62057)
* Better cope with PID 0 when running "docker inspect" to look for
the process id for kubelet container

Fix problem that ipvs can't work with hostPort
**What this PR does / why we need it**:
Make ipvs proxy mode can work with pods that have hostPort.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#61938#60688 and #60305 are related too.
**Special notes for your reviewer**:
IPVS proxier will create dummy device named `kube-ipvs0`, which will maintain all ipvs virtual service address. That means all ipvs maintained clusterIP/externalIP/ingress will be treat as local address.
Then if we have a pod with hostPort, cni will attach this rule to `PREROUTING` chain:
```
KUBE-HOSTPORTS all -- 0.0.0.0/0 0.0.0.0/0 /* kube hostport portals */ ADDRTYPE match dst-type LOCAL
```
so if a service have same port with pod's hostport, then this service can't be access.
In this pr, we added `ACCESS` rule for traffic that aim to ipvs virtual service, to prevent those traffic from be blocked by other rules.

```release-note

Make kubelet `ReadLogs` backward compatible.
`containerLogPathLabelKey` label was added in dockershim since 1.5. 121a91eb12
ContainerStatus.LogPath was added since Kubernetes 1.7. c3b52267ca
I believe it is safe to reply on this field without backward compatibility issue. And `crictl` is using it as well https://github.com/kubernetes-incubator/cri-tools/blob/master/cmd/crictl/logs.go#L88.
With this change, in the future, kubelet `ReadLogs` will be backward compatible as long as the log format is backward compatible.

kubelet: logs: do not wait when following terminated container
Currently, a `kubectl logs -f` on a terminated container will output the logs, wait 5 seconds (`stateCheckPeriod`), then return. The 5 seconds delay should not occur as the container is terminated and unable to generate additional log messages.
This PR puts a check at the beginning of `waitLogs()` to avoid doing the wait when the container is not running.

divide statically known typer from dynamically derived restmapper
The CLI factory conflated a statically known typer and a dynamically derived restmapper. This produced confusion and unnecessary indirection. This pull separates dynamically known from statically known.
A future pull will continue the separation of in the builder to indicate the points of variability for clients, which should logically be limited to a negotiated serializer for decoding and an object typer.
