**What this PR does / why we need it**:
Currently, if you `make build`, etcd is not properly version checked because `etcd -version` does multi-line output. This output cannot be version compared. This small change fixes that.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

Fix caching of go dirs during build
Sometimes when you press `^C` during `make` the subsequent attempt to run `make` hangs due to zero-sized cache file for `ALL_GO_DIRS` var in Makefile.generated_files:
```
vagrant@devbox:~/work/kubernetes/src/k8s.io/kubernetes (master *%) $ KUBE_JUNIT_REPORT_DIR=/tmp/art KUBE_COVER=y make test
# hangs...
^CMakefile:279: recipe for target 'generated_files' failed
make: *** [generated_files] Interrupt
vagrant@devbox:~/work/kubernetes/src/k8s.io/kubernetes (master *%) $ ls -l .make/all_go_dirs.mk
-rw-rw-r-- 1 vagrant vagrant 0 Aug 18 15:03 .make/all_go_dirs.mk
```
Corresponding process subtree looks like the following:
```
└─make test
└─make -f Makefile.generated_files generated_files
└─bash -c grep --color=never -l '+k8s:deepcopy-gen=' | xargs -n1 dirname | sort -u
├─grep --color=never -l +k8s:deepcopy-gen=
├─sort -u
└─xargs -n1 dirname
```
Let's remove the cache file if `cache_go_dirs.sh` gets interrupted.

e2e-runner: Get GCI builtin k8s version from GCS
**What this PR does / why we need it**:
The GCI release qualification tests use builtin k8s version to run tests. They used to get the builtin version by parsing descriptions of the test images, but that's unreliable because the description format could change. This PR makes it to read a file checked in GCS that has the exact k8s version number.

The implicit registration of Prometheus metrics for request count and latency have been removed, and a plug-able interface was added. If you were using our client libraries in your own binaries and want these metrics, add the following to your imports in the main package: "k8s.io/pkg/client/metrics/prometheus".

**What this PR does / why we need it**: This is an implementation of the [image provenance proposal](https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/image-provenance.md). It also includes the API definitions by @Q-Lee from https://github.com/kubernetes/kubernetes/pull/30241
**Special notes for your reviewer**:
Please note that this is the first admission controller to make use of the admission controller config file (`--admission-controller-config-file`). I have defined a format for it but we may want to double check it's adequate for future use cases as well.
The format defined is:
```
{
"imagePolicy": {
"kubeConfigFile": "path/to/kubeconfig/for/backend",
"allowTTL": 50, # time in s to cache approval
"denyTTL": 50, # time in s to cache denial
"retryBackoff": 500, # time in ms to wait between retries
"defaultAllow": true # determines behavior if the webhook backend fails
}
}
```

add --raw for kubectl get
Adds a `--raw` option to `kubectl get` that allow you specify your URI, but use the transport built by `kubectl`. This is especially useful when working with secured environments that require authentication and authorization to hit non-api endpoints. For example, `kubect get --raw /metrics` or if you want to debug a watch with a view at the exact data `kubectl get --raw '/api/v1/namespaces/one/replicationcontrollers?watch=true'`.

Move UTs that block on apiserver to integration tests.
In validating etcd.v3client we had uncovered that a change in the behavior of the client https://github.com/coreos/etcd/issues/6162 , caused a number of unit tests to fail. These test failures were due to the fact that the unit tests were trying to standup a apiserver even though there was no etcd backend stood up.
This PR simply shuffles those tests to integration tests, which is where they should be.
