add client-ca to configmap in kube-public
Client CA information is not secret and it's required for any API server trying to terminate a TLS connection. This pull adds the information to configmaps in `kube-public` that look like this:
```yaml
apiVersion: v1
data:
client-ca.crt: |
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
requestheader-allowed-names: '["system:auth-proxy"]'
requestheader-client-ca-file: |
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
requestheader-extra-headers-prefix: '["X-Remote-Extra-"]'
requestheader-group-headers: '["X-Remote-Group"]'
requestheader-username-headers: '["X-Remote-User"]'
kind: ConfigMap

fix service spec for kube api server
For the auto generated kube api-server service, the service spec re-uses the service port itself. The endpoint is created correctly using public port. Fix the service also because there are some plugin controllers that react to service spec itself.
Before fix:
```
sh-4.2# kubectl get endpoints
NAME ENDPOINTS AGE
kubernetes 172.17.0.2:8443,172.17.0.2:8053,172.17.0.2:8053 20h
sh-4.2# kubectl get services kubernetes -o json
...
...
"spec": {
"clusterIP": "172.30.0.1",
"ports": [
{
"name": "https",
"port": 443,
"protocol": "TCP",
"targetPort": 443 ## <--- same as port, even if the endpoint really means 8443
},
{
"name": "dns",
"port": 53,
"protocol": "UDP",
"targetPort": 8053
},
{
"name": "dns-tcp",
...
```
After fix:
```
"spec": {
"clusterIP": "172.30.0.1",
"ports": [
{
"name": "https",
"port": 443,
"protocol": "TCP",
"targetPort": 8443 # <-- fixed, now matches the endpoint object
},
{
"name": "dns",
"port": 53,
"protocol": "UDP",
"targetPort": 8053
},
{
"name": "dns-tcp",

Promote TokenReview to v1
Peer to https://github.com/kubernetes/kubernetes/pull/40709
We have multiple features that depend on this API:
- [webhook authentication](https://kubernetes.io/docs/admin/authentication/#webhook-token-authentication)
- [kubelet delegated authentication](https://kubernetes.io/docs/admin/kubelet-authentication-authorization/#kubelet-authentication)
- add-on API server delegated authentication
The API has been in use since 1.3 in beta status (v1beta1) with negligible changes:
- Added a status field for reporting errors evaluating the token
This PR promotes the existing v1beta1 API to v1 with no changes
Because the API does not persist data (it is a query/response-style API), there are no data migration concerns.
This positions us to promote the features that depend on this API to stable in 1.7

The authentication.k8s.io API group was promoted to v1
