fix stateful set pod recreation and event spam (#123809) 
* fix pods tracking and internal error checking in statefulset tests

* fix stateful set pod recreation and event spam

- do not emit events when pod reaches terminal phase
- do not try to recreate pod until the old pod has been removed from
  etcd storage

* fix conflict race in statefulset rest update

statefulset controller does less requests per sync now and thus can
reconcile status faster, thus resulting in a higher chance for conflicts

StatefulSet: Cleanup the complex defer function updating the status 
In the long term, the complex defer function makes the code harder to
maintain as code after it should take that into account. This removes
the complex defer function updating the status of a statefulset.

89bb7d8454 Honor the RevisionHistoryLimit in StatefulSetSpec 
The StatefulSet controller cleans up ControllerRevisions at the end of
the reconcile loop. If something goes wrong during reconcile, it bails
out without actually performing this step. This commit moves the cleanup
to a deferred function call to guarantee it will be executed.

Fixes issue: https://github.com/kubernetes/kubernetes/issues/85690

Move from glog to klog 
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
  * github.com/kubernetes/repo-infra
  * k8s.io/gengo/
  * k8s.io/kube-openapi/
  * github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

45eeaab715 Fixes a bug where RollingUpdateStrategy combined with Parallel pod management allows for more than one Pod to be unready during update.
