Fix godep race in local builds
**What this PR does / why we need it**:
This fixes a small race condition when building a godep version other than the latest. As you're building godep once, and then building it again after checkout, this can cause inconsistency in the version selected for use. This fix tells the first `go get` to only download and not build. Then we build manually after checking out the target version.

kubeadm: Rename some flags for beta UI and fixup some logic
**What this PR does / why we need it**:
In this PR:
- `--api-advertise-addresses` becomes `--apiserver-advertise-address`
- The API Server's logic here is that if the address is `0.0.0.0`, it chooses the host's default interface's address. kubeadm here uses exactly the same logic. This arg is then passed to `--advertise-address`, and the API Server will advertise that one for the service VIP.
- `--api-port` becomes `--apiserver-bind-port` for clarity

HPA Controller: Use Custom Metrics API
This commit switches over the HPA controller to use the custom metrics
API. It also converts the HPA controller to use the generated client
in k8s.io/metrics for the resource metrics API.
In order to enable support, you must enable
`--horizontal-pod-autoscaler-use-rest-clients` on the
controller-manager, which will switch the HPA controller's MetricsClient
implementation over to use the standard rest clients for both custom
metrics and resource metrics. This requires that at the least resource
metrics API is registered with kube-aggregator, and that the controller
manager is pointed at kube-aggregator. For this to work, Heapster
must be serving the new-style API server (`--api-server=true`).
Before this merges, this will need kubernetes/metrics#2 to merge, and a godeps update to pull that in.
It's also semi-dependent on kubernetes/heapster#1537, but that is not required in order for this to merge.
**Release note**:
```release-note
Allow the Horizontal Pod Autoscaler controller to talk to the metrics API and custom metrics API as standard APIs.

Add apps/v1beta1 deployments with new defaults
This pull introduces deployments under `apps/v1beta1` and fixes#23597 and #23304.
TODO:
* [x] - create new type `apps/v1beta1.Deployment`
* [x] - update kubectl (stop, scale)
* [ ] - ~~new `kubectl run` generator~~ - this will only duplicate half of generator code, I suggest replacing current to use new endpoint
* [ ] - ~~create extended tests~~ - I've added integration and cmd tests verifying new endpoints
* [ ] - ~~create `hack/test-update-storage-objects.sh`~~ - see above
This is currently blocked by https://github.com/kubernetes/kubernetes/pull/38071, due to conflicting name `v1beta1.Deployment`.
```release-note
Introduce apps/v1beta1.Deployments resource with modified defaults compared to extensions/v1beta1.Deployments.
```

This commit adds the staging repos to the GOPATH in
hack/verify-godeps.sh. This allows vendored librarys
to depend on staging repos and not break verify-godeps.
This also adds `hack/godep-restore.sh`, which acts like
`godep restore`, but sets the GOPATH appropriate as well.

This PR adds a new environmental variable ENABLE_CRI for customizing CRI
**What this PR does / why we need it**:
This PR adds a new environmental variable `ENABLE_CRI` for customizing CRI (e.g. switching between dockershim and dockertools) and sets `--enable-cri=true` by default.
**Which issue this PR fixes**
Fixes#42315.
**Release note**:
```release-note
NONE

Maybe we should also cherry-pick this to 1.6 branch.

Fix update stage
This PR addressed following problems:
1. Removes comments from all staging godeps and makes sure that they are not placed there. This saves false positive during update when `Comment` field is cut by one digit.
2. Moves updating staging to a separate script (`hack/update-all-staging.sh`), `hack/update-all.sh` only runs verification of staging deps.

Extend experimental support to multiple Nvidia GPUs
Extended from #28216
```release-note
`--experimental-nvidia-gpus` flag is **replaced** by `Accelerators` alpha feature gate along with support for multiple Nvidia GPUs.
To use GPUs, pass `Accelerators=true` as part of `--feature-gates` flag.
Works only with Docker runtime.
```
1. Automated testing for this PR is not possible since creation of clusters with GPUs isn't supported yet in GCP.
1. To test this PR locally, use the node e2e.
```shell
TEST_ARGS='--feature-gates=DynamicKubeletConfig=true' FOCUS=GPU SKIP="" make test-e2e-node
```
TODO:
- [x] Run manual tests
- [x] Add node e2e
- [x] Add unit tests for GPU manager (< 100% coverage)
- [ ] Add unit tests in kubelet package

clean up generic apiserver options
Clean up generic apiserver options before we tag any levels. This makes them more in-line with "normal" api servers running on the platform.
Also remove dead example code.

New GKE certificates controller.
