SCTP support implementation for Kubernetes
**What this PR does / why we need it**: This PR adds SCTP support to Kubernetes, including Service, Endpoint, and NetworkPolicy.
**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#44485
**Special notes for your reviewer**:
**Release note**:
```release-note
SCTP is now supported as additional protocol (alpha) alongside TCP and UDP in Pod, Service, Endpoint, and NetworkPolicy.
```
The requested Service Protocol is checked against the supported protocols of GCE Internal LB. The supported protocols are TCP and UDP.
SCTP is not supported by OpenStack LBaaS. If SCTP is requested in a Service with type=LoadBalancer, the request is rejected. Comment style is also corrected.
SCTP is not allowed for LoadBalancer Service and for HostPort. Kube-proxy can be configured not to start listening on the host port for SCTP: see the new SCTPUserSpaceNode parameter
changed the vendor github.com/nokia/sctp to github.com/ishidawataru/sctp. I.e. from now on we use the upstream version.
netexec.go compilation fixed. Various test cases fixed
SCTP related conformance tests removed. Netexec's pod definition and Dockerfile are updated to expose the new SCTP port(8082)
SCTP related e2e test cases are removed as the e2e test systems do not support SCTP
sctp related firewall config is removed from cluster/gce/util.sh. Variable name sctp_addr is corrected to sctpAddr in pkg/proxy/ipvs/proxier.go
cluster/gce/util.sh is copied from master
Events have long shown the most data of the core objects in their output, but that data is of varying use
to a user. Following the principle that events are intended for the system to communicate information back
to the user, and that Message is the primary human readable field, this commit alters the default columns
to ensure event is shown with the most width.
1. Events are no longer sorted in the printer (this was a bug and was broken with paging and server side
rendering)
2. Only the last seen, type, reason, kind, and message fields are shown by default, which makes the
message prominent
3. Source, subobject, count, and first seen are only shown under `-o wide`
4. The duration fields were changed to be the more precise output introduced for job duration (2-3 sig figs)

Fix DeletionTimestamp printing
**What this PR does / why we need it**:
I found a bug that `ObjectMeta.DeletionTimestamp` is not displayed correctly because it's a future time but it uses the time difference until now. So I fixed it by calculating the time difference from now instead of until now.
Before this fix:
```
Name: test-pod-7bd594bd96-hf5kk

Termination Grace Period: 30s

```
After this fix:
```

```
Could you consider merging it?
We heavily use preemptible jobs in my company and knowing deletion time and grace periods is really important when jobs trap `SIGTERM` and decide if it should continue to run until the deletion time or just stop immediately.

Improve job describe and get output
For get, condense completions and success into a single column, and
print the job duration. Use a new variant of ShortHumanDuration that
shows more significant digits, since duration matters more for jobs.
```
NAME COMPLETIONS DURATION AGE
image-mirror-origin-v3.10-1529985600 1/1 47s 42m

image-pruner-1529971200 1/1 60m 4h
```
The completions column can be:
```
COMPLETIONS
0/1 # completions nil or 1, succeeded 0
1/1 # completions nil or 1, succeeded 1
0/3 # completions 3, succeeded 1
1/3 # completions 3, succeeded 1
0/1 of 30 # parallelism of 30, completions is nil
```
Update describe to show the completion time and the duration.

Completed At: Mon, 25 Jun 2018 21:00:34 -0400

```
This is more useful than the current output:

update tests to be specific about the versions they are testing
When setting up tests, you want to rely on your own scheme. This eliminates coupling to floating versions which gives unnecessary flexibility in most cases and prevents testing all the versions you need.

Refactor and simplify generic printer for unknown objects

@kubernetes/sig-cli-pr-reviews part of the general refactoring for server side print
Refactors and removes the need for the more complex old code,
temporarily limits what output is shown for truly unknown objects (a
follow up change will allow server side handling and generic fallback),
and removes all of the generic printers in favor of a single code path.

Remove old node role label that is not used by kubeadm
**What this PR does / why we need it**:
This label hasn't been used by kubeadm since v1.5.
v1.5 support was dropped when v1.6 arrived due to a potential security flaw and the earlier alpha status.
So this label hasn't been used for around three months.
It makes sense to remove it in time for v1.8, could already have been done for v1.7

add ContainerRuntimeVersion to `kubectl get nodes -o=wide` output
**What this PR does / why we need it**: adds container runtime version to `kubectl get nodes -o=wide` output as a way to surface more node-level information
When upgrading to a new container runtime version (docker 1.11 -> docker 1.12) or when experimenting with a different container runtime version (experimenting with rkt in a docker cluster), it's useful for cluster operators to see which nodes are running which container runtime version. `kubectl get nodes -o=wide` already provides kernel and OS version, and I believe adding container runtime version would be good.
**Release note**:
```release-note
container runtime version has been added to the output of `kubectl get nodes -o=wide` as `CONTAINER-RUNTIME`

Wrap HumanReadablePrinter in tab output unless explicitly asked not to

Get command now uses metadata x-kubernetes-print-columns, if present, in Openapi schema
to format output for a resource. This functionality is guarded by a boolean

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.

Add a server side Get operation
Implement proposal kubernetes/community#363
```release-note
The Kubernetes API supports retrieving tabular output for API resources via a new mime-type `application/json;as=Table;v=v1alpha1;g=meta.k8s.io`. The returned object (if the server supports it) will be of type `meta.k8s.io/v1alpha1` with `Table`, and contain column and row information related to the resource. Each row will contain information about the resource - by default it will be the object metadata, but callers can add the `?includeObject=Object` query parameter and receive the full object. In the future kubectl will use this to retrieve the results of `kubectl get`.
```
