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.

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()
```
The key to path mapping allows pod to specify different name (thus location) of each secret.
At the same time refactor the volume plugin to use AtomicWritter to project secrets to files in a volume.
Update e2e Secrets test, the secret file permission has changed from 0444 to 0644
Remove TestPluginIdempotent as the AtomicWritter is responsible for secret creation

Add init containers to pods
This implements #1589 as per proposal #23666
Incorporates feedback on #1589, creates parallel structure for InitContainers and Containers, adds validation for InitContainers that requires name uniqueness, and comments on a number of implications of init containers.
This is a complete alpha implementation.

[e2e] kubectl stdin
Problem: Currently kubectl heavily relies on files which have to be (for lack of a better word :):):)) "written" to the file system. This hinders adoption of something like gobindata, by forcing an intermediary generated-assets directory type thing.
Solution: Lets migrate `kubectl.go` testing over to using standard input streams.

Add pod condition PodScheduled to detect situation when scheduler tried to schedule a Pod, but failed
Set `PodSchedule` condition to `ConditionFalse` in `scheduleOne()` if scheduling failed and to `ConditionTrue` in `/bind` subresource.

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`.
