Promotes Source IP preservation for Virtual IPs from Beta to GA
Fixes#33625. Feature issue: kubernetes/features#27.
Bullet points:
- Declare 2 fields (ExternalTraffic and HealthCheckNodePort) that mirror the ESIPP annotations.
- ESIPP alpha annotations will be ignored.
- Existing ESIPP beta annotations will still be fully supported.
- Allow promoting beta annotations to first class fields or reversely.
- Disallow setting invalid ExternalTraffic and HealthCheckNodePort on services. Default ExternalTraffic field for nodePort or loadBalancer type service to "Global" if not set.
**Release note**:
```release-note
Promotes Source IP preservation for Virtual IPs to GA.
Two api fields are defined correspondingly:
- Service.Spec.ExternalTrafficPolicy <- 'service.beta.kubernetes.io/external-traffic' annotation.
- Service.Spec.HealthCheckNodePort <- 'service.beta.kubernetes.io/healthcheck-nodeport' annotation.

add singular resource names to discovery
Adds the singular resource name to our resource for discovery. This is something we've discussed to remove our pseudo-pluralization library which is unreliable even for english and really has no hope of properly handling other languages or variations we can expect from TPRs and aggregated API servers.
This pull simply adds the information to discovery, it doesn't not re-wire any RESTMappers.
@kubernetes/sig-cli-misc @kubernetes/sig-apimachinery-misc @kubernetes/api-review
```release-note
API resource discovery now includes the `singularName` used to refer to the resource.

Add Host field to TCPSocketAction
Currently, TCPSocketAction always uses Pod's IP in connection. But when a pod uses the host network, sometimes firewall rules may prevent kubelet from connecting through the Pod's IP.
This PR introduces the 'Host' field for TCPSocketAction, and if it is set to non-empty string, the probe will be performed on the configured host rather than the Pod's IP. This gives users an opportunity to explicitly specify 'localhost' as the target for the above situations.
```release-note
Add Host field to TCPSocketAction

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

Admission Controller: Add Pod Preset
Based off the proposal in https://github.com/kubernetes/community/pull/254
cc @pmorie @pwittrock
TODO:
- [ ] tests
**What this PR does / why we need it**: Implements the Pod Injection Policy admission controller
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
**Special notes for your reviewer**:
**Release note**:
```release-note
Added new Api `PodPreset` to enable defining cross-cutting injection of Volumes and Environment into Pods.
```
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

Add ClassName attributes to PV and PVC
This just adds new attributes to PV/PVC. Real code that uses the attributes instead of beta annotations will follow when we agree on the attribute names / style.

Include all user.Info data in CSR object
In order to use authorization checks to auto-approve CSRs in the future, we need all the info from the user.Info interface.
This mirrors the API fields in the TokenReview API used to return user info, and in the SubjectAccessReview API we use to check authorization.
```release-note
The CertificateSigningRequest API added the `extra` field to persist all information about the requesting user. This mirrors the fields in the SubjectAccessReview API used to check authorization.
