This fix allows Reflector/Informer callers to detect API errors using the standard Go errors.As unwrapping methods used by the apimachinery helper methods. Combined with a custom WatchErrorHandler, this can be used to stop an informer that encounters specific errors, like resource not found or forbidden.

* client-go: Remove unreachable return
Due to the way the switch statement is done,
the return at the end of the function will neverbe reached.

* client-go: Refactor for clarity
Fixed one instance where the error message should be lowercase.
Made the fields in the struct literal more explicit

https://github.com/kubernetes/kubernetes/pull/87795 most likely
unintentionally increased the log level of "Starting reflector" and
"Stopping reflector", with the result that since Kubernetes 1.21
clients have printed that message by default. This is undesirable, we
should use the original level 3 again.

Currently when ListAndWatch() receives a connection refused error, it is
assumed to be due to the apiserver being transiently unresponsive. In
situations where a controller is running outside the k8s cluster it's
controlling, it is more common for the controller to lose connection
permanently to the apiserver and needs to exponentially backoff its
retry rather than continously spamming logs with Watch attempts that
will never succeed.

When creating an informer, this adds a way to add custom error handling, so that
Kubernetes tooling can properly surface the errors to the end user.

It was previously possible to instantiate `Reflector` with
`*unstructured.Unstructured` as the expected type but this did not
support checking that event objects were of the correct API
type (e.g. if event object was `v1.Pod` in `Unstructured` form but
`v1.Service` was expected). This commit adds support for providing a
GVK via an `Unstructured` expected type to compare with the GVK of
event objects. The GVK will also be used in reflector log output.

This warning comes from Reflector watchHandler, from the apiserver error that
indicates a watch was restarted. This happens when etcd drops the connection
and resources are relisted. This informs the user that the watchers are
operating properly, so should be logged as Info rather than Warning.

- 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
