Also includes other improvements:
- Makefile rule to run tests against remote instance using existing host or image
- Makefile will reuse an instance created from an image if it was not torn down
- Runner starts gce instances in parallel with building source
- Runner uses instance ip instead of hostname so that it doesn't need to resolve
- Runner supports cleaning up files and processes on an instance without stopping / deleting it
- Runner runs tests using `ginkgo` binary to support running tests in parallel

Always skew the client when running version-skew tests
As mentioned in the comments:
- for upgrade jobs, we want kubectl to be at the same version as master.
- for client skew tests, we want to use the skewed kubectl (that's what we're testing).
So, remove gate on `JENKINS_USE_SKEW_KUBECTL`, and always use the skewed `kubectl`.
This should go in before https://github.com/kubernetes/test-infra/pull/109.
We want to continuously validate Docker releases (#25215), on GCI. This change
adds a new test config variable, `KUBE_GCI_DOCKER_VERSION`, through which we can
specify which version of Docker we want to run on the master and nodes. This
change also patches the Jenkins e2e-runner with the ability to fetch the latest
Docker (pre)release, and sets the aforementioned variable accordingly.

Don't allow deps with no discernible license
This updates the few deps we had with no LICENSE file to current versions that do have that file. It also disallows new deps without obvious licenses.

Attach/Detach Controller Kubelet Changes
This PR contains changes to enable attach/detach controller proposed in #20262.
Specifically it:
* Introduces a new `enable-controller-attach-detach` kubelet flag to enable control by attach/detach controller. Default enabled.
* Removes all references `SafeToDetach` annotation from controller.
* Adds the new `VolumesInUse` field to the Node Status API object.
* Modifies the controller to use `VolumesInUse` instead of `SafeToDetach` annotation to gate detachment.
* Modifies kubelet to set `VolumesInUse` before Mount and after Unmount.
* There is a bug in the `node-problem-detector` binary that causes `VolumesInUse` to get reset to nil every 30 seconds. Issue https://github.com/kubernetes/node-problem-detector/issues/9#issuecomment-221770924 opened to fix that.
* There is a bug here in the mount/unmount code that prevents resetting `VolumeInUse in some cases, this will be fixed by mount/unmount refactor.
* Have controller process detaches before attaches so that volumes referenced by pods that are rescheduled to a different node are detached first.
* Fix misc bugs in controller.
* Modify GCE attacher to: remove retries, remove mutex, and not fail if volume is already attached or already detached.
Fixes#14642, #19953
```release-note
Kubernetes v1.3 introduces a new Attach/Detach Controller. This controller manages attaching and detaching volumes on-behalf of nodes that have the "volumes.kubernetes.io/controller-managed-attach-detach" annotation.
A kubelet flag, "enable-controller-attach-detach" (default true), controls whether a node sets the "controller-managed-attach-detach" or not.

Fixes#26526 - hack/update-api-reference-docs.sh
I opened a Pull request to fix this issue https://github.com/kubernetes/kubernetes/issues/26526
The problem is that the update script ignores white spaces but the verify script doesn't which leads to a strange behaviour -> you use the update script but the verify script tells you that the api docs are not up to date.
This PR contains Kubelet changes to enable attach/detach controller control.
* It introduces a new "enable-controller-attach-detach" kubelet flag to
enable control by controller. Default enabled.
* It removes all references "SafeToDetach" annoation from controller.
* It adds the new VolumesInUse field to the Node Status API object.
* It modifies the controller to use VolumesInUse instead of SafeToDetach
annotation to gate detachment.
* There is a bug in node-problem-detector that causes VolumesInUse to
get reset every 30 seconds. Issue https://github.com/kubernetes/node-problem-detector/issues/9
opened to fix that.
Add it as a special case package root and import the license file. This was
the only UNKNOWN license, prior to the change to not look at upstream repo
state.
This change recovers some of the side effects of
https://github.com/kubernetes/kubernetes/pull/26197, i.e., keeps the defaults of
`NODE_IMAGE` and `NODE_IMAGE_PROJECT` to `MASTER_IMAGE` and
`MASTER_IMAGE_PROJECT`, for backward compatibility. Although it keeps
`OS_DISTRIBUTION` defaulting to `gci`, the default settings of these vars are
moved to `cluster/gce/util.sh` and conditioned on `OS_DISTRIBUTION==gci`.

Don't set the env var CC when not cross-compiling
I noticed that this script was trying to use `arm-linux-gnueabi-gcc` also when running natively on arm.
When running natively, `CC` should always be `gcc` (which also is the default)
Also added `federation-controller-manager` to the static list, I think someone forgot to do that.
