As cited in
https://github.com/kubernetes/dns/issues/174 - this is documented to
work, and I don't see why it shouldn't work. We allowed the definition
of headless services without ports, but apparently nobody tested it very
well.
Manually tested clusterIP services with no ports - validation error.
Manually tested services with negative ports - validation error.
New tests failed, output inspected and verified. Now pass.
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)

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-mirror-origin-v3.11-1529985600 1/1 74s 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.
```
Start Time: Mon, 25 Jun 2018 20:00:05 -0400
Completed At: Mon, 25 Jun 2018 21:00:34 -0400

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

image-mirror-origin-v3.11-1529982000 1 1 54m
image-pruner-1529971200 1 1 3h
```
```release-note

Implement a stub server printer for CRDs
This wires up TableConvertor to CRDs and puts a basic implementation in place for custom paths. However, since our OpenAPISchema can't store OpenAPI extension fields there is no way to expose the custom column piece that get.go supports today (`x-kubernetes-print-columns`). That piece can be implemented separately and needs discussion.
As this is purely exposing the default interface, very low risk. Will add an e2e test that covers this under a registered CRD.
@soltysh @sttts @kubernetes/sig-api-machinery-pr-reviews
A couple of options for wiring up the actual definition:
1. add a new "extensions" map to spec.validation
1. Downside: won't handle future child nested fields, not the correct schema
2. try to change the OpenAPISchema3 field to support extensions
1. Would require a breaking protobuf change, is also very difficult
2. Could store the entire schema as opaque JSON and then parse on load (might be the right thing anyway)
3. Support this as an annotation in 1.11 - `alpha.customresource.k8s.io/x-kubernetes-print-columns` like the CLI

```release-note
The `meta.k8s.io/v1alpha1` objects for retrieving tabular responses from the server (`Table`) or fetching just the `ObjectMeta` for an object (as `PartialObjectMetadata`) are now beta as part of `meta.k8s.io/v1beta1`. Clients may request alternate representations of normal Kubernetes objects by passing an `Accept` header like `application/json;as=Table;g=meta.k8s.io;v=v1beta1` or `application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1`. Older servers will ignore this representation or return an error if it is not available. Clients may request fallback to the normal object by adding a non-qualified mime-type to their `Accept` header like `application/json` - the server will then respond with either the alternate representation if it is supported or the fallback mime-type which is the normal object response.

kubectl: Add Terminating state to PVs
kubectl shows PV `Terminating` status, just like Pod and [PVC](https://github.com/kubernetes/kubernetes/pull/55873)
**What this PR does / why we need it**:
We will postpone PV deletion if it is bound to a PVC, see #58743, so we may keep PV waiting for deletion for a longer time than before so users should know what is going on.

kubectl should show something when a PVC has a deletion timestamp and is
waiting for deletion. This patch follows Pod - it adds Terminating state.
For easier discovery of errors, finalizers are printed in `kubectl describe
pvc`.

Refactor and simplify generic printer for unknown objects
The first two commits are part of other PRs
@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`
```
