enable resource name and service account cases for impersonation
Adds the resource name check since that attribute was added for authorization. Also adds a check against a separate resource for service accounts. Allowing impersonation of service accounts to use a different resource check places control of impersonation with the same users to have the power to get the SA tokens directly.

Kubelet eviction flag parsers and tests
The first two commits are from https://github.com/kubernetes/kubernetes/pull/24559 that have achieved LGTM.
The last commit is only part that is interesting, it adds the parsing logic to handle the flags, and reserves `pkg/kubelet/eviction` for eviction manager logic.

test/e2e/addon_update: Respect KUBE_SSH_USER
This change makes the e2e tests more consistent as the other ones all already respected this variable.
I didn't do the larger change of re-factoring it to use `framework.SSH` because getting the `scp` portion working there has some significant complexity. If I find time, I'd like to go back and do it since this test needs a little ❤️

Move godeps to vendor/

cluster/images/hyperkube: create symlink for each server
Add a kubelet symlink so that the hyperkube image can appear as a kubelet image. https://github.com/kubernetes/kubernetes/issues/24510
a) it doesn't need it
b) changing CWD to a path with symlinks breaks deep within ginkgo, where it
crafts a relative path to ../../../../../../platforms/amd64/whatever which then
traverses the physical path not the symlinked one, and breaks.
Our `realpath` and `readlink -f` functions (required only because of MacOS,
thanks Steve) were poor substitutes at best. Mostly they were downright
broken. This thoroughly overhauls them and adds a test (in comments, since we
don't seem to have shell tests). For all the interesting cases I could think
of, the fakes act just like the real thing.
Then use those and canonicalize KUBE_ROOT. In order to make recursive calls of
our shell tool not additively grow `pwd` we have to essentially make the
sourcing of init.sh idempotent.

kubelet: Remove redundant `Container.Created`
As far as I can tell, this has been supplanted by a) the `DockerJSON.CreatedAt` field and b) the
`ContainerStatus.CreatedAt`, where the first is used for creating the
second.
The `.Created` field was only written to as far as I can see.

Introduce events flag for describers
Printing events for a given object is not always needed. Thus, introducing --show-events=false to ``kubectl describe`` to skip events printing.

Abstract node side functionality of attachable plugins
- Create PhysicalAttacher interface to abstract MountDevice and
WaitForAttach.
- Create PhysicalDetacher interface to abstract WaitForDetach and
UnmountDevice.
- Expand unit tests to check that Attach, Detach, WaitForAttach,
WaitForDetach, MountDevice, and UnmountDevice get call where
appropriet.
Physical{Attacher,Detacher} are working titles suggestions welcome. Some other thoughts:
- NodeSideAttacher or NodeAttacher.
- AttachWatcher
- Call this Attacher and call the Current Attacher CloudAttacher.
- DeviceMounter (although there are way too many things called Mounter right now :/)
This is to address: https://github.com/kubernetes/kubernetes/pull/21709#issuecomment-192035382

Support persisting config from kubecfg AuthProvider plugins
Plumbs through an interface to the plugin that can persist a `map[string]string` config for just that plugin. Also adds `config` to the AuthProvider serialization type, and `Login()` to the AuthProvider plugin interface.
Modified the gcp AuthProvider to cache short-term access tokens in the kubecfg file.
Builds on #23066

kubectl describe: show multiple labels/annotations on multiple lines
Small UX improvement: when there is more than one label/annotation, it's more readable to see them on the different lines.
Before:
```console
$ kubectl describe svc
Name: s2i-test
Namespace: test2
Labels: app=s2i-test,foo=bar
...
```
After:
```console
$ kubectl describe svc
Name: s2i-test
Namespace: test2
Labels: app=s2i-test
foo=bar
...
```
This change affects output of the labels/annotations in many of the sub-commands of the `kubectl describe`.

add namespace index for cache
@wojtek-t
Implement in this approach make the change of lister.go small, but we should replace all `NewInformer()` to `NewIndexInformer()`, even when someone not want to filter by namespace(eg. gc_controller and scheduler). Any suggestion?

Reimplement 'pause' in C - smaller footprint all around
Statically links against musl. Size of amd64 binary is 3560 bytes.
I couldn't test the arm binary since I have no hardware to test it on, though I assume we want it to work on a raspberry pi.
This PR also adds the gcc5/musl cross compiling image used to build the binaries.

Add subPath to mount a child dir or file of a volumeMount
Allow users to specify a subPath in Container.volumeMounts so they can use a single volume for many mounts instead of creating many volumes. For instance, a user can now use a single PersistentVolume to store the Mysql database and the document root of an Apache server of a LAMP stack pod by mapping them to different subPaths in this single volume.
Also solves https://github.com/kubernetes/kubernetes/issues/20466.
