Run goimport for the whole repo
While removing GOMAXPROC and running goimports, I noticed quite a lot of other files also needed a goimport format. Didn't commit `*.generated.go`, `*.deepcopy.go` or files in `vendor`

Handle container terminated but pod still running in conditions
Sometimes when you have a pod with more than one container, and the container runs and terminates really fast, `PodContainerRunning` can go into a state where the pod indicates it's still running, but the container is already terminated. Handle that condition by returning `ErrContainerTerminated` when it happens.
Added a PriorityRESTMapper that operates off of discovery information. I
made an auxiliary data type and function to help collect and organize
the information.

Track object modifications in fake clientset
Fake clientset is used by unit tests extensively but it has some
shortcomings:
- no filtering on namespace and name: tests that want to test objects in
multiple namespaces end up getting all objects from this clientset,
as it doesn't perform any filtering based on name and namespace;
- updates and deletes don't modify the clientset state, so some tests
can get unexpected results if they modify/delete objects using the
clientset;
- it's possible to insert multiple objects with the same
kind/name/namespace, this leads to confusing behavior, as retrieval is
based on the insertion order, but anchors on the last added object as
long as no more objects are added.
This change changes core.ObjectRetriever implementation to track object
adds, updates and deletes.
Some unit tests were depending on the previous (and somewhat incorrect)
behavior. These are fixed in the following few commits.

pkg/client/leaderelection: log err when retrieving endpoint
The leader election code currently suppresses errors when trying to retrieve an endpoint. This can lead to difficult to debug situations.

Setting TLS1.2 minimum because TLS1.0 and TLS1.1 are vulnerable
TLS1.0 is known as vulnerable since it can be downgraded to SSL
https://blog.varonis.com/ssl-and-tls-1-0-no-longer-acceptable-for-pci-compliance/
TLS1.1 can be vulnerable if cipher RC4-SHA is used, and in Kubernetes it is, you can check it with
`
openssl s_client -cipher RC4-SHA -connect apiserver.k8s.example.com:443
`
https://www.globalsign.com/en/blog/poodle-vulnerability-expands-beyond-sslv3-to-tls/
Test suites like Qualys are reporting this Kubernetes issue as a level 3 vulnerability, they recommend to upgrade to TLS1.2 that is not affected, quoting Qualys:
`
RC4 should not be used where possible. One reason that RC4 was still being used was BEAST and Lucky13 attacks against CBC mode ciphers in
SSL and
TLS. However, TLSv 1.2 or later address these issues.

Also change to explicit return without named return values.
A recent change tries to separate resync and relist. The motivation
was to avoid triggering relist when a resync is required.
However, the change is not effective since it stops the watcher. As hongchao
mentioned in the original comment, today's storage interface will not deliever
any progress notification to the watch chan. So any watcher that does not receive
events for the last few seconds will not be able to catch up from the previous
index after a hard close since the index of the last received event is out of
the cache window inside etcd2.
This pull request tries to fix this issue by not stoping watcher when a resync is
required.

Adding support objects for integrating dynamic client the kubectl builder
Kubectl will try to decode into `runtime.VersionedObjects`, so the `UnstructuredJSONScheme` needs to handle that intelligently.
Kubectl's builder also needs a `meta.RESTMapper` and `runtime.Typer`. The `meta.RESTMapper` requires a `runtime.ObjectConvertor` (spelling?) that works with `runtime.Unstructured`. The mapper and typer required discovery info, so I just put that in the kubectl util package since it didn't really seem to fit anywhere else.

Make ThirdPartyResource a root scoped object
ThirdPartyResource (the registration of a third party type) belongs at the cluster scope. It results in resource handlers installed in every namespace, and the same name in two namespaces collides (namespace is ignored when determining group/kind).
ThirdPartyResourceData (an actual instance of that type) is still namespace-scoped.
This PR moves ThirdPartyResource to be a root scope object. Someone previously using ThirdPartyResource definitions in alpha should be able to move them from namespace to root scope like this:
setup (run on 1.2):
```
kubectl create ns ns1
echo '{"kind":"ThirdPartyResource","apiVersion":"extensions/v1beta1","metadata":{"name":"foo.example.com"},"versions":[{"name":"v8"}]}' | kubectl create -f - --namespace=ns1
echo '{"kind":"Foo","apiVersion":"example.com/v8","metadata":{"name":"MyFoo"},"testkey":"testvalue"}' | kubectl create -f - --namespace=ns1
```
export:
```
kubectl get thirdpartyresource --all-namespaces -o yaml > tprs.yaml
```
remove namespaced kind registrations (this shouldn't remove the data of that type, which is another possible issue):
```
kubectl delete -f tprs.yaml
```
... upgrade ...
re-register the custom types at the root scope:
```
kubectl create -f tprs.yaml
```
Additionally, pre-1.3 clients that expect to read/write ThirdPartyResource at a namespace scope will not be compatible with 1.3+ servers, and 1.3+ clients that expect to read/write ThirdPartyResource at a root scope will not be compatible with pre-1.3 servers.
The codec factory should support two distinct interfaces - negotiating
for a serializer with a client, vs reading or writing data to a storage
form (etcd, disk, etc). Make the EncodeForVersion and DecodeToVersion
methods only take Encoder and Decoder, and slight refactoring elsewhere.
In the storage factory, use a content type to control what serializer to
pick, and use the universal deserializer. This ensures that storage can
read JSON (which might be from older objects) while only writing
protobuf. Add exceptions for those resources that may not be able to
write to protobuf (specifically third party resources, but potentially
others in the future).
The test recorder should be thread safe in case it's used in multiple
goroutines. This does not serve to ensure any order of recorded events,
only to prevent golang race detector to crash when two events are emitted by
concurrent goroutines.
Add accessor methods that implement pkg/api/unversioned.ObjectKind,
pkg/api/meta.Object, pkg/api/meta.Type and pkg/api/meta.List.
Removed the convenience fields since writing to them was not reflected
in serialized JSON.

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.

This patch fixes it and makes the option work on those cases too by making
sure no CA/CAData is added when it shouldn't.
To make it pass the unit test, following is previous failing log for unit test
_output/dockerized/go/src/k8s.io/kubernetes/pkg/client/unversioned/daemon_sets_test.go:20: imported and not used: "k8s.io/kubernetes/pkg/client/unversioned"

The message as it is framed right now does not make any sense for the
end users of our system. It might even lead to confusion. So this is
attempt to make the error message less confusing.
Update the Deployments' API types, defaulting code, conversions, helpers
and validation to use ReplicaSets instead of ReplicationControllers and
LabelSelector instead of map[string]string for selectors.
Also update the Deployment controller, registry, kubectl subcommands,
client listers package and e2e tests to use ReplicaSets and
LabelSelector for Deployments.
I can't revert with github which says "Sorry, this pull request couldn’t be

Reverts commit: 0c191e787b
Move type LabelSelector and type LabelSelectorRequirement from pkg/apis/extensions
This avoids an import loop when Job (and later DaemonSet, Deployment, ReplicaSet)
are moved out of extensions to new api groups.
Also Move LabelSelectorAsSelector utility from pkg/apis/extensions/ to pkg/api/unversioned/
Also its test.
Also LabelSelectorOp* constants.
Also the pkg/apis/extensions/validation functions ValidateLabelSelectorRequirement and
ValidateLabelSelector move to pkg/api/unversioned
The related type in pkg/apis/extensions/v1beta1/ is staying there. I might move
it in another PR if neccessary.
Combine the fields that will be used for content transformation
(content-type, codec, and group version) into a single struct in client,
and then pass that struct into the rest client and request. Set the
content-type when sending requests to the server, and accept the content
type as primary.
Will form the foundation for content-negotiation via the client.
When job.spec.completions is nil, only
one task needs to succeed for the job to succeed,
and parallelism can be scaled freely during runtime.
Added tests.
Release Note:
This causes two minor changes to the API.
First, unset parallelism previously was defaulted to be
equal to completions. Now it always defaults to 1 if unset.
Second, having parallelism=N and completions unset would previously
be defaulted to 1 completion and N parallelism.
(this is not something we expect people to do, though)
Now, no defaulting occurs in that case, and the job's
behavior is different (any completion causes success).
