Fix cAdvisorPort, 0 is a valid option
wrt #11710, this maintains the current default if nobody provides the flag, but allows explicitly passing 0.
/cc @farcaller @vishh @liggitt @antoineco @philips
/assign @liggitt @vishh
```release-note
Fixes a bug with cAdvisorPort in the KubeletConfiguration that prevented setting it to 0, which is in fact a valid option, as noted in issue #11710.

This commit adds the new API status conditions to the API types.
The field exists as a field in autoscaling/v2alpha1, and is
round-tripped through an annotation in autoscaling/v1.

prevent illegal verb/name combinations in default policy rules
Names aren't presented with some kinds of "normal" verbs. This prevents people from making common mistakes.
@timothysc as I noted in your pull. This will prevent some classes of errors.

Add local storage (scratch space) allocatable support
This PR adds the support for allocatable local storage (scratch space).
This feature is only for root file system which is shared by kubernetes
componenets, users' containers and/or images. User could use
--kube-reserved flag to reserve the storage for kube system components.
If the allocatable storage for user's pods is used up, some pods will be
evicted to free the storage resource.
This feature is part of local storage capacity isolation and described in the proposal https://github.com/kubernetes/community/pull/306
**Release note**:
```release-note
This feature exposes local storage capacity for the primary partitions, and supports & enforces storage reservation in Node Allocatable

Dynamic webhook admission control plugin
Unit tests pass.
Needs plumbing:
* [ ] service resolver (depends on @wfender PR)
* [x] client cert (depends on ????)
* [ ] hook source (depends on @caesarxuchao PR)
Also at least one thing will need to be renamed after Chao's PR merges.
```release-note
Allow remote admission controllers to be dynamically added and removed by administrators. External admission controllers make an HTTP POST containing details of the requested action which the service can approve or reject.

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.

@derekwaynecarr since most of these are related to the kubelet

Admissionregistration nonnamespace
The two types are root scoped.
Just adding a couple of tags. Other code is generated.
This PR adds the check for local storage request when admitting pods. If
the local storage request exceeds the available resource, pod will be
rejected.

Set Kubelet Disk Defaults for the 1.7 release
The `--low-diskspace-threshold-mb` flag has been depreciated since 1.6.
This PR sets the default to `0`, and sets defaults for disk eviction based on the values used for our [e2e tests](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/services/kubelet.go#L145).
This also removes the custom defaults for vagrant, as the new defaults should work for it as well.
/assign @derekwaynecarr
cc @vishh
```release-note
By default, --low-diskspace-threshold-mb is not set, and --eviction-hard includes "nodefs.available<10%,nodefs.inodesFree<5%"
```
To properly register the types in the admission API group we need to
create an "install" package and wire it up. This is required by the
webhook admission controller being developed as part of

This commit regenerates the protobuf as per the recent generation
changes (removing erroneous imports, adding k8s.io/metrics), and
syncs the changes to client-go (which also ensures that client-go
protobuf IDL has the correct package names).
