Remove 'all namespaces' meaning of empty list in PodAffinityTerm
Removes the distinction between `null` and `[]` for the PodAffinityTerm#namespaces field (option 4 discussed in https://github.com/kubernetes/kubernetes/issues/43203#issuecomment-287237992), since we can't distinguish between them in protobuf (and it's a less than ideal API)
Leaves the door open to reintroducing "all namespaces" function via a dedicated field or a dedicated token in the list of namespaces
Wanted to get a PR open and tests green in case we went with this option.
Not sure what doc/release-note is needed if the "all namespaces" function is not present in 1.6
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

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.

Move post processing/backward compatibility of openapi out of generic package
Post processing step was put into generic package and was the same for both k8s api server and federation api server. They have different backward compatibility list of types. This PR move that step out of generic package and put it in each server's file.

Add version to OpenAPI spec
OpenAPI is missing a version string. It should follow kubernetes version. It is a bugfix that need to be cherrypicked in 1.5 too.

Optional configmaps and secrets
Allow configmaps and secrets for environment variables and volume sources to be optional
Implements approved proposal c9f881b7bb
Release note:
```release-note
Volumes and environment variables populated from ConfigMap and Secret objects can now tolerate the named source object or specific keys being missing, by adding `optional: true` to the volume or environment variable source specifications.

move pkg/fields to apimachinery
Purely mechanical move of `pkg/fields` to apimachinery.
Discussed with @lavalamp on slack. Moving this an `labels` to apimachinery.
@liggitt any concerns? I think the idea of field selection should become generic and this ends up shared between client and server, so this is a more logical location.

Generate OpenAPI definition for inlined types
Currently OpenAPI definition generator ignores any type's member with an empty json name tag. However, most (if not all) of these types also have "inline" json tag. That means we should inline their members into parent type's OpenAPI definition instead of ignoring them. This resulted in many types missing common parameters such as "Name". It look something serious to me for OpenAPI spec and I suggest we merge and cherry-pick this into 1.5 release branch as soon as possible.

Add GroupVersion tags to OpenAPI spec and remove all specs except main one
Tags are used as a grouping mechanism in OpenAPI. We generated one spec per GroupVersion before for this grouping but by adding those tags in this PR, those files have no use. We can always add them back if there were a use-case for them.
**Release note**:
```release-note
Deprecate OpenAPI spec for GroupVersion endpoints in favor of single spec /swagger.json
```
Reference: #13414
Previously we refused to emit 'autoConvert_*' functions if any field was not
convertible. The way around this was to write manual Conversion functions, but
to do so safely you must handle every fields. Huge opportunity for errors.
This PR cleans up the filtering such that it only operates on types that should
be converted (remove a lot of code) and tracks when fields are skipped. In
that case, it emits an 'autoConvert' function but not a public 'Convert'
function. If there is no manual function, the compile will fail.
This also means that manual conversion functions can call autoConvert functions
and then "patch up" what they need.

Correct versioned.Event output in Swagger
Fixes#24240
```release-note
The value of the `versioned.Event` object (returned by watch APIs) in the Swagger 1.2 schemas has been updated from `*versioned.Event` which was not expected by many client tools. The new value is consistent with other structs returned by the API.
