Add storage.k8s.io/v1 API
This is combined version of reverted #40088 (first 4 commits) and #41646. The difference is that all controllers and tests use old `storage.k8s.io/v1beta1` API so in theory all tests can pass on GKE.
Release note:
```release-note
StorageClassName attribute has been added to PersistentVolume and PersistentVolumeClaim objects and should be used instead of annotation `volume.beta.kubernetes.io/storage-class`. The beta annotation is still working in this release, however it will be removed in a future release.

Keep entries of apimachinery in client-go's Godeps.json
1. copy.sh now copies staging/ to a temp dir, creates snapshots for them, and then adds the temp dir to GOPATH before running `godep save`. This way, we don't need the `go list` check added in #41987 so that's removed @sttts.
2. copy.sh fills the entries for k8s.io/apimachinery with dummy SHA1 in client-go's Godeps.json. The publish robot will later fill the actually published one.
3. copy.sh removes the entire `_vendor` from client-go. We cannot keep `_vendor` because it makes hard to use the `git filter-branch` magic for client-go, because the filtered commits might contain changes to `_vendor` while client-go only has `vendor/`.
Some notes on point 3: the robot will restore the vendor/ later, but exclude k8s.io/* and glog, so that users retrieving client-go with `go get` won't end up with multiple copies of them. I think this should be a ***general rule*** for published k8s.io/* repos: every published repos should have complete Godeps.json with latest commit hashes of other k8s.io/* repos, but vendor/k8s.io/* and vendor/glog will be removed from all repos.

apiserver/pkg/server: include scheme in insecure self client config
Noticed this during bootkube development: https://github.com/kubernetes-incubator/bootkube/issues/325
In Go 1.8's `url.Parse` became more strict, and `url.Parse("127.0.0.1:8080")` now fails.
https://beta.golang.org/doc/go1.8#net_urlhttps://play.golang.org/p/dw_cPeotG4
Accidentally compiled bootkube with 1.8 and tracked a panic down to the loopback client config. Though we're still using the old "genericapiserver", this seems to be translated from the old one.
The actual panic we observed was
```

I don't actually know if this is the correct fix or if there should be changes to `NewForConfigOrDie`. Am looking for comments more than anything.

@jbeda @luxas you got a good way to test this? It must not be covered in normal e2e or we'd've seen the issue before.
The RC/RS Listers still use selectors, because this is the behavior
expected by callers. This clarifies the meaning of the returned list.
Some callers may need to switch to using GetControllerOf() instead,
but that is a separate, case-by-case issue.

Re-writing of the resolv.conf file generated by docker
Fixes#17406
Docker 1.12 will contain feature "The option --dns and --net=host should not be mutually exclusive" (docker/docker#22408)
This patch adds optional support for this ability in kubelet (for now in case of "hostNetwork: true" set all dns settings are ignored if any).
To enable feature use newly added kubelet flag: --allow-dns-for-hostnet=true
Introduced chages:
1. Re-writing of the resolv.conf file generated by docker.
Cluster dns settings aren't passed anymore to docker api in all cases, not only for pods with host network:
the resolver conf will be overwritten after infra-container creation to override docker's behaviour.
2. Added new one dnsPolicy - 'ClusterFirstWithHostNet', so now there are:
- ClusterFirstWithHostNet - use dns settings in all cases, i.e. with hostNet=true as well
- ClusterFirst - use dns settings unless hostNetwork is true
- Default

stop spamming logs on restart of api server
**What this PR does / why we need it**:
This PR reduces an excessive amount of log spam on startup of any API server with larger amounts of content. We have experienced server restart times ~5 minutes that is a consequence of us tracing each directory in etcd during our initial decoding. This spams the journald process, and results in much of those messages getting rate limited and dropped, and making actual problems much harder to debug. This stops us logging discrete keys in favor of just knowing that an operation was slow for the particular object type (which is enough information!)
this PR also makes it so we know what trace operation was ended in our log messages!
sample log now:
```
Trace "decodeNodeList *[]api.PolicyBinding" (started 2017-02-20 22:20:33.98771112 +0000 UTC)

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).

apiserver: self-signed in-memory cert for loopback
We had complicated logic before to find a matching (SNI- or server-) cert for the loopback device. In the worst case, bootstrapping failed because the provided certs didn't have the binding IP or localhost.
We now pass an artifical `ServerName` "apiserver-loopback-client" with the loopback client and install a self-signed in-memory cert+key into the server for that hostname. The client accepts the corresponding cert.

client-gen: independent scheme for clientsets
This PR adds a clientset internal scheme instead of using `pkg/api.Scheme`. **The clientset API stays the same.**
In detail:
- introduce a scheme for each clientset, i.e. do not use `pkg/api.Scheme+Registry+Codec+ParameterCodecs`.
This makes it easier to compose client-go's clientset (which is rewritten in `staging/copy.sh` and therefore hardcoded to use `k8s.io/client-go/pkg/api.Scheme+Registry+Codecs+ParameterCodecs`) with third-party clientsets (kube-aggregator, openshift, federation) which are not rewritten using `copy.sh` as all of them are self-contained and therefore relocatable.
This fixes https://github.com/kubernetes/kubernetes/pull/41403/files#diff-76edfb07dee54ff7ddeda25c33c10d29R81 and prepares client-gen for use in OpenShift.
- register types into the clientset scheme via `AddToScheme` for versioned clientsets. This decouples the client-go clients from announce+registration (internal clients continue using announce+registry and apigroup installers).
This reduces complexity for client-go, possibly remove the necessity for the announce+register machinery for many use-cases, maybe even to delete it mid-term.
- port federation and testgroup `install/install.go` to `announced.GroupMetaFactory` in order to have a proper `Install.Install(...)` func for registration.
With the first change it's easy to add the types of one clientset to the scheme of the other using the `clientset/scheme.AddToScheme` method. This allows to use cross-clientset `runtime.RawExtensions`:
```golang
import (
"k8s.io/client-go/kubernetes"
clientsetscheme "k8s.io/client-go/kuberentes/scheme"
aggregatorclientsetscheme "k8s.io/kube-aggregator/pkg/client/clientset_generated/clientset/scheme"
)
kclientset, _ := kubernetes.NewForConfig(c)
aggregatorclientsetscheme.AddToScheme(clientsetscheme.Scheme)
```
Kubernetes types with a `RawExtension` can en/decode aggregator types after this.
TODO:
- [x] fix fake clientsets
- [x] get the `*Options` types registered correctly for core, compare DO-NOT-MERGE commit.
- [x] get prefered version right in internal client. Do we need all versions registered in the internal client to support negotiation?
- [x] run `staging/copy.sh` and run tests: https://github.com/kubernetes/kubernetes/pull/41744
- ~~[ ] fixup usage through-out the code-base~~
- **Follow-up**: move `import_known_versions.go` files somewhere such that import of the `api.Scheme` package automatically installs the apigroups. It looks like we depended on the import fo the clientset for this purpose.

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.

make kube-aggregator run as static pod for local-up-cluster
Runs the kube-aggregator as a static pod for local-up-cluster. Looks like someone broke kubectl negotiation again, so I'll fix that up separately.

apiserver: further cleanup of apiserver storage plumbing
- move kubeapiserver`s `RESTOptionsFactory` back to EtcdOptions by adding a `AddWithStorageFactoryTo`
- factor out storage backend `Config` construction from EtcdOptions
- move all `StorageFactory` related code into server/storage subpackage.
In short: remove my stomach ache about `kubeapiserver.RESTOptionsFactory`.

stop senseless negotiation
Most client commands don't respect a negotiated version at all. If you request a particular version, then of course it should be respected, but if you have none to request, then the current negotiation step doesn't return anything useful so we may as well have nothing so we can at least detect the situation.
@jwforres @kubernetes/sig-cli-pr-reviews
Added a TODO to make the negotiate function useful. I think I'm inclined to remove it entirely unless someone can come up with a useful reason to have it.

copy pkg/util/logs to apiserver
This is a copy, not a move. API servers need to be able to init the logs, but so do clients. It would be weird to have the client-side commands depending on the server side logs utilities.

Houston, we've had a problem here. ObjectMeta had used the reflection fallback path for deepcopy for probably some time.
Remark: my original plan for https://github.com/kubernetes/kubernetes/pull/36412 was/is to rebase that during the master branch freeze for 1.6 and get it merged just before master opens again.

make round trip testing generic
RoundTrip testing is something associated with a scheme and everyone who writes an API will want to do it. In the end, we should wire each API group separately in a test scheme and have them all call this general function. Once `kubeadm` is out of the main scheme, we'll be able to remove the one really ugly hack.

Add unit tests for interactive edit command
Before updating edit to use unstructured objects and use generic JSON patching, we need better test coverage of the existing paths. This adds unit tests for the interactive edit scenarios.
This PR adds:
* Simple framework for recording tests for interactive edit:
* record.go is a tiny test server that records editor and API inputs as test expectations, and editor and API outputs as playback stubs
* record_editor.sh is a shell script that sends the before/after of an interactive `vi` edit to the test server
* record_testcase.sh (see README) starts up the test server, sets up a kubeconfig to proxy to the test server, sets EDITOR to invoke record_editor.sh, then opens a shell that lets you use `kubectl edit` normally
* Adds test cases for the following scenarios:
- [x] no-op edit (open and close without making changes)
- [x] try to edit a missing object
- [x] edit single item successfully
- [x] edit list of items successfully
- [x] edit a single item, submit with an error, re-edit, submit fixed successfully
- [x] edit list of items, submit some with errors and some good, re-edit errors, submit fixed
- [x] edit trying to change immutable things like name/version/kind, ensure preconditions prevent submission
- [x] edit in "create mode" successfully (`kubectl create -f ... --edit`)
- [x] edit in "create mode" introducing errors (`kubectl create -f ... --edit`)
* Fixes a bug with edit printing errors to stdout (caught when testing stdout/stderr against expected output)
Follow-ups:
- [ ] clean up edit code path
- [ ] switch edit to use unstructured objects
- [ ] make edit fall back to jsonmerge for objects without registered go structs (TPR, unknown versions of pods, etc)
- [ ] add tests:
- [ ] edit TPR
- [ ] edit mix of TPR and known objects
- [ ] edit known object with extra field from server
- [ ] edit known object with new version from server

move --runtime-config to kubeapiserver
`--runtime-config` is only useful if you have a lot of API groups in one server. If you have a single API group in your server (the vast majority of aggregated API servers), then the flag is unneeded and relatively complex. This moves it to closer to point of use.

federation: Refactoring namespaced resources deletion code from kube ns controller and sharing it with fed ns controller
Ref https://github.com/kubernetes/kubernetes/issues/33612
Refactoring code in kube namespace controller to delete all resources in a namespace when the namespace is deleted. Refactored this code into a separate NamespacedResourcesDeleter class and calling it from federation namespace controller.
This is required for enabling cascading deletion of namespaced resources in federation apiserver.
Before this PR, we were directly deleting the namespaced resources and assuming that they go away immediately. With cascading deletion, we will have to wait for the corresponding controllers to first delete the resources from underlying clusters and then delete the resource from federation control plane. NamespacedResourcesDeleter has this waiting logic.

update negotiation to reflect current kubectl state
Very few things actually require negotiation, but the client-cache attempts it all the time. If you've explicitly requested one, you still fail. If you haven't requested one and the server doesn't have one, you still get the client behavior. After this, if you haven't requested one and the client and server don't have one, you simply get an empty you can interpret how you choose.
@lavalamp without this, you're unable to use `kubectl` against arbitrary servers.

switch admission serialized config to an apiserver type
Switches the kube admission config from componentconfig to the new `apiserver.k8s.io` group so that all API servers can use the shared configuration. This switch external serialization, but it does not move the code that reads the config. I'd like to do that as a follow-on.

Allows a transformer (such as an encrypter) to force an update if a new
key is in use, thus allowing simple writes to the REST layer to
trivially migrate keys.
This adds a new value transformer to the etcd2 store that can transform
the value from etcd on read and write. This will allow the store to
implement encryption at rest or otherwise transform the value prior to
persistence.
