Add new `--server-dry-run` flag to `kubectl apply` so that the request will be sent to the server with the dry-run flag (alpha), which means that changes won't be persisted.

Add ability to build with runtime coverage instrumentation
**What this PR does / why we need it**:
This PR adds the ability to instrument a subset of kubernetes binaries to report code coverage information. The specific use-case is to help determine coverage of our end-to-end Conformance tests, as well as provide data that can be used to help determine where to focus. This PR focuses on making it possible to build with instrumentation; collecting and using the generated coverage data will be done in later PRs. For more details as to the intent, see the [design doc](https://docs.google.com/document/d/1FKMBFxz7vtA-6ZgUkA47F8m6yR00fwqLcXMVJqsHt0g/edit?usp=sharing) (google doc; requires kubernetes-dev membership).
Specifically, this PR adds a new `KUBE_BUILD_WITH_COVERAGE` make variable, which when set will cause `kube-apiserver`, `kube-controller-manager`, `kube-scheduler`, `kube-proxy` and `kubelet` to be built with coverage instrumentation. These coverage-instrumented binaries will flush coverage information to disk every five seconds, defaulting to a temporary directory unless the `KUBE_COVERAGE_FILE` environment variable is set at launch, in which case it will write to that file instead.
The mechanism used to achieve coverage instrumentation is to build the targeted binaries as "unit tests" with coverage enabled, and then rigging the unit tests to just execute the binary's usual entry point. This is implemented only for the bash build system.

add make targets for building server images
**What this PR does / why we need it**: Adds `make release-images` and `make quick-release-images`, which allow building the docker-wrapped images without building a full release. Without these you can either use `make {quick}-release` and build test tarballs etc, or hack around in the build system yourself. Using this can be considerably faster if you just want to build the binaries and images, and not the release tarballs etc.

**Special notes for your reviewer**:
Per the discussion in https://groups.google.com/d/msg/kubernetes-sig-storage-wg-csi/x5CchIP9qiI/D_TyOrn2CwAJ the API is being added to the staging directory of the `kubernetes/kubernetes` repo because the consumers will be attach/detach controller and possibly kubelet, but it will be installed as a CRD (because we want to move in the direction where the API server is Kubernetes agnostic, and all Kubernetes specific types are installed).
**Release note**:
```release-note
Introduce CSI Cluster Registration mechanism to ease CSI plugin discovery and allow CSI drivers to customize Kubernetes' interaction with them.
```

Update `kubectl get` sorter to deal with server-side printing
**Release note**:
```release-note
NONE
```
### Why?
Currently, we default to non-server-side printing when sorting items in `kubectl get`. This means that instead of taking advantage of having the server tell `kubectl` how to display information, `kubectl` falls back to using hardcoded resource types to figure out how to print its output. This does not really work with resources that `kubectl` does not know about, and it goes against our goal of snipping any dependencies that `kubectl` has on the core repo.
This patch adds a sorter capable of dealing with Table objects sent by the server when using "server-side printing".
A few things left to take care of:
- ~~[ ] When printing `all` resources, this implementation does not handle sorting every single Table object, but rather _only_ the rows in each object. As a result, output will contain sorted resources of the same _kind_, but the overall list of mixed resources will _not_ itself be sorted. Example:~~
```bash
$ kubectl get all --sort-by .metadata.name
NAME READY STATUS RESTARTS AGE
# pods here will be sorted:
pod/bar 0/2 Pending 0 31m
pod/foo 1/1 Running 0 37m
NAME DESIRED CURRENT READY AGE
# replication controllers here will be sorted as well:
replicationcontroller/baz 1 1 1 37m
replicationcontroller/buz 1 1 1 37m
# ... but the overall mixed list of rc's and pods will not be sorted
```
This occurs because each Table object received from the server contains all rows for that resource _kind_. We would need a way to build an ambiguous Table object containing all rows for all objects regardless of their type to have a fully sorted mixed-object output.
- [ ] handle sorting by column-names, rather than _only_ with jsonpaths (Tracked in https://github.com/kubernetes/kubernetes/issues/68027)

Move kubeproxy ComponentConfig external types to `k8s.io/kube-proxy`
**What this PR does / why we need it**:
This PR implements most of kubernetes/community#2354 for the kube-proxy.
The PR:
- Moves k8s.io/kubernetes/pkg/proxy/apis/kubeproxyconfig as-is to k8s.io/kubernetes/pkg/proxy/apis/config as agreed
- Moves the external types to the new staging repo k8s.io/kube-proxy, in the k8s.io/kube-proxy/config/v1beta1 package.
- Makes k8s.io/kubernetes/pkg/proxy/apis/config/v1beta1 source the types from k8s.io/kube-proxy/config/v1beta1. The defaulting and conversion code is kept in this package as before.
- All references to these packages have been updated.

Fix unstructured metadata accessors to respect omitempty semantics
Fixes#67541Fixes#48211Fixes#49075
Follow up of #67562
`ObjectMeta` has fields with `omitempty` json tags. This means that when the fields have zero values, they should not be persisted in the object.
Before this PR, some of the metadata accessors for unstructured objects did not respect these semantics i.e they would persist a field even if it had a zero value.
This PR updates the accessors so that the field is removed from the unstructured object map if it contains a zero value.
