Don't dump everything in kubemarks
Don't dump all events etc. in kubemark failures, those are useless anyway with that amount of data.

Fix panic in auth test failure
I got a spurious failure in the webhook integration test, but couldn't see the error returned because a panic was hit that assumed a body was always returned with the response

E2e tests for GKE cluster with local SSD.
The test cover node pool with local SSD creation and scheduling a pod that writes and reads from it. Pod access local disk via hostPath.

kubelet/cadvisor: Refactor cadvisor disk stat/usage interfaces.
basically
1) cadvisor struct will know what runtime the kubelet is, passed in via additional argument to New()
2) rename cadvisor wrapper function to DockerImagesFsInfo() to ImagesFsInfo() and have linux implementation choose a label based on the runtime inside the cadvisor struct
2a) mock/fake/unsupported modified to take the same additional argument in New()
3) kubelet's wrapper for the cadvisor wrapper is renamed in parallel
4) make all tests use new interface

Cache Webhook Authentication responses
Add a simple LRU cache w/ 2 minute TTL to the webhook authenticator.
Kubectl is a little spammy, w/ >= 4 API requests per command. This also prevents a single unauthenticated user from being able to DOS the remote authenticator.

Extend secrets volumes with path control
As per [1] this PR extends secrets mapped into volume with:
* key-to-path mapping the same way as is for configmap. E.g.
```
{
"apiVersion": "v1",
"kind": "Pod",
"metadata": {
"name": "mypod",
"namespace": "default"
},
"spec": {
"containers": [{
"name": "mypod",
"image": "redis",
"volumeMounts": [{
"name": "foo",
"mountPath": "/etc/foo",
"readOnly": true
}]
}],
"volumes": [{
"name": "foo",
"secret": {
"secretName": "mysecret",
"items": [{
"key": "username",
"path": "my-username"
}]
}
}]
}
}
```
Here the ``spec.volumes[0].secret.items`` added changing original target ``/etc/foo/username`` to ``/etc/foo/my-username``.
* secondly, refactoring ``pkg/volumes/secrets/secrets.go`` volume plugin to use ``AtomicWritter`` to project a secret into file.

Check status of framework.CheckPodsRunningReady
Check status of framework.CheckPodsRunningReady and fail test if it's false, instead of silently
ignoring the failure.
This doesn't fix whatever is causing the pod not to start in #17523 but it does fail the test as soon as it detects the pod didn't start, instead of allowing the testing to proceed.

I removed the netexec and goproxy pods from the proxy exec test. Instead
it now runs kubectl locally and the proxy is running in-process. Since
Go won't proxy for localhost requests, this test cannot pass if the API
server is local. However it was already disabled for local clusters.

SchedulerPredicates e2e test: be more verbose about requested resource
When ``validates resource limits of pods that are allowed to run [Conformance]`` test is run, logs could give more information about requested resource and say it is for cpu and in mili units.
cpu is stored in m units here:
```
nodeToCapacityMap[node.Name] = capacity.MilliValue()
```

Add a timeout to the node e2e Ginkgo test runner
Also add a few debugging statements to indicate progress.
Should help prevent #25639, since we'll timeout tests before Jenkins times out the build.

gcr.io/google_containers/mounttest: use Stat instead of Lstat
The current ``mt.go`` implementation use ``os.Lstat`` instead of ``os.Stat`` which does not read symlinks. Since implementation of ``AtomicWriter`` (which relies on existence of symlinks), the updated implementation of secret volume using the ``AtomicWriter`` can not be tested for secret file permission. Replacing ``Lstat`` with ``Stat`` allows to read symlinks and return permissions of target file. The change affects ``--file_perm`` and ``--file_mode`` options only.
``mounttest`` image is currently used by:
##### downwardapi_volume.go
- e2e: Downward API volume
- version: 0.6
- args: --file_content, --break_on_expected_content, --retry_time, --file_content_in_loop
##### empty_dir.go
- e2e: EmptyDir volumes
- version: 0.5
- args: --file_perm, --file_perm, ...
##### host_path.go
- e2e: hostPath
- version: 0.6
- args: --file_mode, ...
##### configmap.go
- e2e: ConfigMap
- version: 0.6
- args: --file_content, --break_on_expected_content, --retry_time, --file_content_in_loop
##### service_accounts.go
- e2e: ServiceAccounts
- version: 0.2
- args: --file_content
Some of the e2e tests use at least one of the affected options. Locally, I have updated all version of mounttest images to 0.7. All e2e tests pass with the new image.
- create 100 PV, ranging from 0 to 99GB; create 1 PVC to claim 50GB. Verify only one PV is bound and rest are pending
- create 2 PVs with different access modes (RWM, RWO), 1 PVC to claim RWM PV. Verify RWM is bound and RWO is not bound.
