Automatic merge from submit-queue

Fix crash in kubectl run

I observed the problem in k8s 1.5.1, but the code is still there, so fixing it.
Here's the old backtrace - happened due to network disconnection during `kubectl run`:

```

Waiting for pod default/alpine1 to be running, status is Pending, pod ready: false
If you don't see a command prompt, try pressing enter.

Adding load balancer src cidrs to GCE cloudprovider

**What this PR does / why we need it**:
As of January 31st, 2018, GCP will be sending health checks and l7 traffic from two CIDRs and legacy health checks from three CIDS. This PR moves them into the cloudprovider package and provides a flag for override.

Another PR will need to be address firewall rule creation for external L4 network loadbalancing #40778

**Which issue this PR fixes**
Step one of #40778
Step one of https://github.com/kubernetes/ingress/issues/197

**Release note**:
```release-note

Non global admission plugin registry

For testing the global state is a problem. This PR turns the actual registry into a struct that must be instantiated. For the beginning, we do this in `pkg/kubeapiserver/admission`. In some follow-up (where we hunt down all globals some day), we will move this into the genericapiserver.

Conversionlint

**What this PR does / why we need it**:
This PR adds a comment placeholder for the exported or public functions in conversion generator files. Such functions without a comment results into golint failure in various generated files. The changes in this patch takes care of about 36 related lint failures. 
Given below is an example lint error, 
zz_generated.conversion.go:91:1: exported function Convert_v1alpha1_Binding_To_servicecatalog_Binding should have comment or be unexported

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
Considering minor changes no issue is created. 

**Special notes for your reviewer**:
Hello, I am trying to fix golint failures as we see them in the kubernetes-incubator/service-catalog project. I have separate PRs opened for lint issues related to other generator code which are in separate libraries like gengo. Thanks!

Edge-based userspace LB in kube-proxy

@thockin @bowei - if one of you could take a look if that PR doesn't break some basic kube-proxy assumptions. The similar change for winuserproxy should be pretty trivial.

And we should also do that for iptables, but that requires splitting the iptables code to syncProxyRules (which from what I know @thockin already started working on so we should probably wait for it to be done).

Move api helpers.go to a subpackage

Part of https://github.com/kubernetes/kubernetes/issues/44065.

This PR moves the pkg/api/helpers.go to its own subpackage. It's mostly a mechanic move, except that
* I removed ConversionError in helpers.go, it's not used by anyone
* I moved the 3 methods of Taint and Toleration to pkg/api/methods.go, and left a TODO saying refactoring these methods to functions.

I'll send a few more PRs to make the k8s.io/kubernetes/pkg/api package only contains the code we want in the k8s.io/api repo, then we can run a [script](a0015fd1be (diff-7a2fbb4371972350ee414c6b88aee1c8)) to cut the new repo.

Add support for IP aliases for pod IPs (GCP alpha feature)

```release-note
Adds support for allocation of pod IPs via IP aliases.

# Adds KUBE_GCE_ENABLE_IP_ALIASES flag to the cluster up scripts (`kube-{up,down}.sh`).

KUBE_GCE_ENABLE_IP_ALIASES=true will enable allocation of PodCIDR ips
using the ip alias mechanism rather than using routes. This feature is currently
only available on GCE.

## Usage
$ CLUSTER_IP_RANGE=10.100.0.0/16 KUBE_GCE_ENABLE_IP_ALIASES=true bash -x cluster/kube-up.sh

# Adds CloudAllocator to the node CIDR allocator (kubernetes-controller manager).

If CIDRAllocatorType is set to `CloudCIDRAllocator`, then allocation
of CIDR allocation instead is done by the external cloud provider and
the node controller is only responsible for reflecting the allocation
into the node spec.

- Splits off the rangeAllocator from the cidr_allocator.go file.
- Adds cloudCIDRAllocator, which is used when the cloud provider allocates
  the CIDR ranges externally. (GCE support only)
- Updates RBAC permission for node controller to include PATCH

Avoid nil user special-casing in unsecured endpoint

The unsecured handler currently adds no `user.Info` to the request context.  That means that anything that tries to authorize actions in the API server currently has to special case nil users to ensure the unsecured localhost endpoint remains capable of performing all actions. 

This PR changes the unsecured localhost endpoint to be treated as a privileged user internally, so that no special casing is required by code inside the authentication layer

I'm not particularly attached to the username. It doesn't bother me for it to have a slightly uncomfortable sounding name.
