HPA Controller: Use Custom Metrics API
This commit switches over the HPA controller to use the custom metrics
API. It also converts the HPA controller to use the generated client
in k8s.io/metrics for the resource metrics API.
In order to enable support, you must enable
`--horizontal-pod-autoscaler-use-rest-clients` on the
controller-manager, which will switch the HPA controller's MetricsClient
implementation over to use the standard rest clients for both custom
metrics and resource metrics. This requires that at the least resource
metrics API is registered with kube-aggregator, and that the controller
manager is pointed at kube-aggregator. For this to work, Heapster
must be serving the new-style API server (`--api-server=true`).
Before this merges, this will need kubernetes/metrics#2 to merge, and a godeps update to pull that in.
It's also semi-dependent on kubernetes/heapster#1537, but that is not required in order for this to merge.
**Release note**:
```release-note
Allow the Horizontal Pod Autoscaler controller to talk to the metrics API and custom metrics API as standard APIs.

auto discovery CA for extension API servers
This is what the smaller pulls were leading to. Only the last commit is unique and I expect I'll still tweak some pod definitions, but this is where I was going.

add aggregation integration test
Wires up an integration test which runs a full kube-apiserver, the wardle server, and the kube-aggregator and creates the APIservice object for the wardle server. Without services and DNS the aggregator doesn't proxy, but it does ensure we don't have an obvious panic or bring up failure.

client-gen: create private registry in fake clientset
This cuts of the laster `k8s.io/kubernetes/pkg/api.{Registry+Scheme+Codecs}` dependency from the clientsets. This enables clientset generation for packages that must not have a dependency onto kubernetes itself.
@deads2k there is more than the namespace checking we discussed: the RESTMapper built from the registry. This introduces a private registry. I try get that out from the normal versioned client as much as possible. I would even like to remove this private registry some day, at best remove all registry code from the client. But that's for another day...

numeric ordering of kubectl outputs
**What this PR does / why we need it**:
Instead of having kubectl listing the pods in a alphabetical way:
foobar-1-build
foobar-10-build
foobar-2-build
foobar-3-build
With the parameter --sort-by '{.metadata.name}' it now gives:
foobar-1-build
foobar-2-build
foobar-3-build
foobar-10-build

add secret option to flag

> This is unfortunately not all flags that could be secrets. The best option would be to add support in spf13/pflag to tag a flag as a secret, and then use that bit to determine the list.

> Also, Command() could be used in contexts that need exact parameters (for subshell execution), so we would need to add a new method or extend the signature here to allow exact flags to be retrieved.
we could add a secret option to the flags.

Refactor printers and describers into their own package.
This sets the stage for using printer code from the server side (decoupled from kubectl) and loosens the coupling between kubectl and the printers. `pkg/printers` contains interfaces and has an import restriction against pulling in API specific code, while `pkg/printers/internalversion` can be used for internal types.
Add a method on `Factory` for retrieving PrinterForCommand which uses the Scheme and RESTMapper from the Factory, not the hardcoded ones. This further separates kubectl from the core API scheme and allows better composition.
Change NamePrinter to use RESTMapper (previously it was hardcoding those conversions). This means that we now return plural resource names (`pods/foo`) but is correct once aliases and shortnames start being returned by the mapper.
This is a prerequisite for server side get, but is pure refactor (contains no new features).

Fix for Support selection of datastore for dynamic provisioning in vS…
Fixes#40558
Current vSphere Cloud provider doesn't allow a user to select a datastore for dynamic provisioning. All the volumes are created in default datastore provided by the user in the global vsphere configuration file.
With this fix, the user will be able to provide the datastore in the storage class definition. This will allow the volumes to be created in the datastore specified by the user in the storage class definition. This field is optional. If no datastore is specified, the volume will be created in the default datastore specified in the global config file.
For example:
User creates a storage class with the datastore
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: slow
provisioner: kubernetes.io/vsphere-volume
parameters:
diskformat: thin
datastore: VMFSDatastore
Now the volume will be created in the datastore - "VMFSDatastore" specified by the user.
If the user creates a storage class without any datastore
kind: StorageClass
apiVersion: storage.k8s.io/v1beta1
metadata:
name: slow
provisioner: kubernetes.io/vsphere-volume
parameters:
diskformat: thin
Now the volume will be created in the datastore which in the global configuration file (vsphere.conf)

add godep manifest files to staging repos
The staging repos should have manifests that match the godeps of kube so we know what they build against. We don't need the actual vendored code, since a sync script on the other side needs to find the correct level of other staging directories and thus requires its own `godep restore && go get && godep save` cycle.
@sttts ptal
@lavalamp @caesarxuchao client-go needs a lot of unwinding to do something similar, but the idea is that you can run an acyclic path to get this updated by copying the types and dependencies with `go list`, then generate the clients, then generate this manifest. Then in your sync script you can pull the proper levels and finish the actual vendoring.

client-go: don't import client auth provider packages
Both of these auth providers are useful for kubectl but not so much for everyone importing client-go. Let users optionally import them (example [0]) and reduce the overall number of imports that client-go requires.
Quick grep seems to imply it wont import it after.

Cleanup client example
**What this PR does / why we need it**:
- Package level `config` variable in `third-party-resources/main.go` is not used, it is shadowed by the one defined in `main()`. Should probably be deleted.
- Package level `kubeconfig ` variable in `out-of-cluster/main.go` is global - make it private to `main()`.
**Which issue this PR fixes**
This fixes https://github.com/kubernetes/client-go/issues/59, except the part about global `api.Scheme`, also adds test with interface check. Supersedes https://github.com/kubernetes/client-go/pull/61.
**Special notes for your reviewer**:
This is my first PR to Kubernetes :)
This change migrates the 'openstack' provider and 'keystone'
authenticator plugin to the newer gophercloud/gophercloud library.
Note the 'rackspace' provider still uses rackspace/gophercloud.

several issues hit while trying to make it easy to register APIs
I was trying to create a script that would register all API versions on a given server and ended up hitting several problems. These are the fixes.
@sttts I suspect that I won't be able to continue down the host-network approach, since that means I won't be able to use in-cluster DNS without some finagling. It *could* be set up (and we make it work as a for instance), but the simple enablement approach will be hosted on the infrastructure. I'll go back to that.
