stop duplicating preferred version order
`GroupMeta` includes two fields for a preferred groupVersion, `.GroupVersion` and `.GroupVersion[0]`. This collapses onto the latter.
@kubernetes/sig-api-machinery-pr-reviews
lots of ripples, but eliminate of duplication is good.

generated code should pass go vet for go1.10

kube-controller-manager defaults --leader-elect to true. We should
do the same for kube-scheduler. kube-scheduler used to have this
set to true, but it got lost during refactoring in:

feat(fakeclient): push event on watched channel on add/update/delete
**What this PR does / why we need it**:
This PR enables watch function for kubernetes [fakeclient](1bcf0b0a22/staging/src/k8s.io/client-go/kubernetes/fake/clientset_generated.go (L88)).
This fake client add watchReactorFunction by wrapping [watch.NewFake](1bcf0b0a22/staging/src/k8s.io/client-go/kubernetes/fake/clientset_generated.go (L98)) which is a `chan Event` but actually nothing pushes objects into this channel. So all watch function called by fake client will never return or never receive any object.
This PR intercepts ReactionFunc of `Create / Update / DeleteActionImpl` and will push the requested object to channel.
Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes#54075
**Special notes for your reviewer**:
**Release note**:
```dev-release-note
enable watch function for fake client
