Upgrades tests use chaosmonkey package and ServiceTestJig
Introduce the `chaosmonkey` e2e package for doing disruptive testing (e.g. upgrade testing) more easily.
- [x] `chaosmonkey` package
- [x] migrate upgrade tests to `chaosmonkey` (using WIP `serviceJig`)
- [x] migrate upgrade tests to use `ServiceTestJig` and `chaosmonkey`
Deferred:
- [ ] make `ServiceTestJig` implement `chaosmonkey.Interface`
- [ ] migrate disruptive services tests to use `ServiceTestJig` and `chaosmonkey`
This provides the extensible framework for #15131. We should now easily be able to add tests (e.g. #6084, #23189).
This is a rewrite of #22446.
cc @mikedanese @quinton-hoole @roberthbailey
Assigning to @thockin, who wrote `ServiceTestJig`.

Let the dynamic client take runtime.Object instead of v1.ListOptions
so that I can pass whatever version of ListOptions to the List/Watch/DeleteCollection methods.

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.

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 ❤️

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`.

kubectl: more sophisticated pod selection for logs and attach
Trying to get the logs or attach to an object other than a pod
will poll forever if that object has no replicas. This commit adds
a 20s timeout for polling.

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.
