add myself and liggitt to pkg/kubelet/certificats OWNERs
For as long a kubelet is using the internal client, this certificate
manager is bound to the kubelet. Once kubelet has moved to client-go we
plan to extract this library to be general purpose. In the meantime,
liggitt and I should handle reviews of this code.

Support grabbing test suite metrics
**What this PR does / why we need it**:
Add support for grabbing metrics that cover the entire test suite's execution.
Update the "interesting" controller-manager metrics to match the
current names for the garbage collector, and add namespace controller
metrics to the list.
If you enable `--gather-suite-metrics-at-teardown`, the metrics file is written to a file with a name such as `MetricsForE2ESuite_2017-05-25T20:25:57Z.json` in the `--report-dir`. If you don't specify `--report-dir`, the metrics are written to the test log output.
I'd like to enable this for some of the `pull-*` CI jobs, which will require a separate PR to test-infra.

AWS: consider instances of all states in DisksAreAttached, not just "running"
Require callers of `getInstancesByNodeNames(Cached)` to specify the states they want to filter instances by, if any. DisksAreAttached, cannot only get "running" instances because of the following attach/detach bug we discovered:
1. Node A stops (or reboots) and stays down for x amount of time
2. Kube reschedules all pods to different nodes; the ones using ebs volumes cannot run because their volumes are still attached to node A
3. Verify volumes are attached check happens while node A is down
4. Since aws ebs bulk verify filters by running nodes, it assumes the volumes attached to node A are detached and removes them all from ASW
5. Node A comes back; its volumes are still attached to it but the attach detach controller has removed them all from asw and so will never detach them even though they are no longer desired on this node and in fact desired elsewhere
6. Pods cannot run because their volumes are still attached to node A
So the idea here is to remove the wrong assumption that callers of `getInstancesByNodeNames(Cached)` only want "running" nodes.
I hope this isn't too confusing, open to alternative ways of fixing the bug + making the code nice.

Require DeleteStrategy for all registry.Store
**What this PR does / why we need it**:
All `registry.Store` objects already set a non-nil `DeleteStrategy`. This change ensures that all future objects do so as well.

In regards to this, why is the `RESTDeleteStrategy` a useless interface (as far as deletion goes)? We cast it to `GarbageCollectionDeleteStrategy` or `RESTGracefulDeleteStrategy` in an attempt to do operations related to deletion, but we have "default" behavior for both of those cases. It should be possible to make `DeleteStrategy` optional by using the other strategies as the `runtime.ObjectTyper` and then defaulting a `nil` `DeleteStrategy` with the expected behavior.
```go
// RESTDeleteStrategy defines deletion behavior on an object that follows Kubernetes
// API conventions.
type RESTDeleteStrategy interface {
runtime.ObjectTyper
}
type GarbageCollectionPolicy string
const (
DeleteDependents GarbageCollectionPolicy = "DeleteDependents"
OrphanDependents GarbageCollectionPolicy = "OrphanDependents"
)
// GarbageCollectionDeleteStrategy must be implemented by the registry that wants to
// orphan dependents by default.
type GarbageCollectionDeleteStrategy interface {
// DefaultGarbageCollectionPolicy returns the default garbage collection behavior.
DefaultGarbageCollectionPolicy() GarbageCollectionPolicy
}
// RESTGracefulDeleteStrategy must be implemented by the registry that supports
// graceful deletion.
type RESTGracefulDeleteStrategy interface {
// CheckGracefulDelete should return true if the object can be gracefully deleted and set
// any default values on the DeleteOptions.
CheckGracefulDelete(ctx genericapirequest.Context, obj runtime.Object, options *metav1.DeleteOptions) bool
}
```

Fixes kubectl cached discovery on Windows
Fixes https://github.com/kubernetes/kubectl/issues/18
The `kubectl` cached discovery makes use of `func (f *File) Chmod(mode FileMode) error` which is not supported and errors out on Windows, making `kubectl get` and potentially a number of other commands to fail miserably on that platform. `os.Chmod` by file name, on the other hand, does not error out and should be used instead.

move CustomResourceDefinitions from alpha to beta
CRDs are built upon the known ThirdPartyResource API with the lessons learned guiding the new shape. Short comings of the old TPR API even have specific tests to ensure that CRDs do not face the same issues. Given that, this API qualifies for beta.

use make slice to store objects to improve efficiency
Signed-off-by: allencloud <allen.sun@daocloud.io>
**What this PR does / why we need it**:
we we know the slice length in advance, I think we had better use make to create the specified length of slice. This will improve some kind of performance. Since if we create a slice with []type{}, we did not know how much space runtime should reserve, since slice implementation should be continuous in memory. While when we make a slice with specified length, runtime would reserve a continuous memory space which will not result in slice movement in case of current space is not enough.
