Use correct home directory on Windows
As of now the `kubectl` config mechanism that saves/loads `~/.kube/config` is broken on Windows, saving the config file in the *current* directory instead of the user's *home* dir. This happens because most Windows don't respect the `HOME` environment variable.
This PR changes the config file loading mechanism to use the recommended way to detect the user home on Windows (`HOMEDRIVE`+`HOMEPATH` or `USERPROFILE`), and adds a migration for users that might be currently relying on existing config files.

A pod never terminated if a container image registry was unavailable
Fixes https://github.com/kubernetes/kubernetes/issues/23742
Fixes https://github.com/kubernetes/kubernetes/issues/22045
Pods will now show proper status when this happens as well:
```
$ cluster/kubectl.sh get pods --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE
test foo-4072956304-1g8qs 0/1 RegistryUnavailable 0 7s
test foo-4072956304-i045g 0/1 RegistryUnavailable 0 7s
test foo-4072956304-qem2n 0/1 RegistryUnavailable 0 7s
```
Where as previously they would never report a reason.
I also removed the "temporary" part of the message because we have no idea if its temporary or permanent.

Add support for 3rd party objects to kubectl
@deads2k @jlowdermilk
Instructions for playing around with this:
Run an apiserver with third party resources turned on (`--runtime-config=extensions/v1beta1=true,extensions/v1beta1/thirdpartyresources=true`)
Then you should be able to:
```
kubectl create -f rsrc.json
```
```json
{
"metadata": {
"name": "foo.company.com"
},
"apiVersion": "extensions/v1beta1",
"kind": "ThirdPartyResource",
"versions": [
{
"apiGroup": "group",
"name": "v1"
},
{
"apiGroup": "group",
"name": "v2"
}
]
}
```
Once that is done, you should be able to:
```
curl http://<server>/apis/company.com/v1/foos
```
```
curl -X POST -d @${HOME}/foo.json http://localhost:8080/apis/company.com/v1/namespaces/default/foos
```
```json
{
"kind": "Foo",
"apiVersion": "company.com/v1",
"metadata": {
"name": "baz"
},
"someField": "hello world",
"otherField": 1
}
```
After this PR, you can do:
```
kubectl create -f foo.json
```
```
kubectl get foos
```
etc.

Migrate to the new conversion generator - part1
This PR contains two commits:
- few more fixes to the generator
- migration of the pkg/api/v1 to use the new generator
The second commit is big, but I reviewed the changes and they contain:
- conversions between types that we didn't even generating conversion between
- changes in how we handle maps/pointers/slices - previously we were explicitly referencing fields, now we are using "shadowing in, out" to make the code more generic
- lack of auto-generated method for ReplicationControllerSpec (because these types are different (*int vs int for Replicas) and a preexisting conversion already exists
Most of issues in the first commit (e.g. adding references to "in" and "out" for slices/maps/points) were discovered by our tests. So I'm pretty confident that this change is correct now.

storage.Interface KV impl. of etcd v3
This is the initial implementation of #22448.
The PR consists of two parts:
- add godep of "clientv3" and "integration" (for testing)
- create new package "etcd3" under "pkg/storage/"
- implement KV methods of storage.Interface using etcd v3 APIs
- Create, Set, Get, Delete, GetToList, List, GuaranteedUpdate

Implement network plugin capabilities hook and shaping capability
Allow network plugins to declare that they handle shaping and that
Kuberenetes should not. I've got an OpenShift PR that handles shaping in OVS but the kubelet code sends nasty pod events because it doesn't think shaping is used since --reconcile-cbr0 is not used with most network plugins.
See https://github.com/openshift/openshift-sdn/pull/266 for the OpenShift implementation.
Allow network plugins to declare that they handle shaping and that
Kuberenetes should not. Will be first used by openshift-sdn which
handles shaping through OVS, but this triggers a warning when
kubelet notices the bandwidth annotations.

rkt: bump rkt version to 1.2.1
Upon bumping the rkt version, `--hostname` is supported. Also we now gets the configs from the rkt api service, so `stage1-image` is deprecated.

allow kubectl cmds to process files recursively, when given a dir
This PR accomplishes two things:
1. It creates a `--recursive` flag for use with certain `kubectl` commands that _currently_ do not process files beyond their first level of children, as seen in the issue https://github.com/kubernetes/kubernetes/issues/19767
2. It enables the ability to use the `--recursive` flag in the `kubectl` commands that currently _only_ support processing a directory up to its first level of children.

Make kubelet use an arch-specific pause image depending on GOARCH
Related to: #22876, #22683 and #15140
@ixdy @pwittrock @brendandburns @mikedanese @yujuhong @thockin @zmerlynn
Add GeneratePodHostNameAndDomain() to RuntimeHelper to
get the hostname of the pod from kubelet.
Also update the logging flag to change the journal match from
_HOSTNAME to _MACHINE_ID.
reqs:
- the kubectl cmd must support the -f | --filename flag
- the kubectl cmd must support visiting a dir one level deep,
or using more than one resource
