2ea105df63 Drop unused EndpointsHandler / EndpointsConfig from pkg/proxy/config 
(Also NoopEndpointSliceHandler since it's no longer possible for a
proxy implementation to no-op EndpointSlice handling.)

7f6fbc4482 Drop broken/no-op proxyconfig.EndpointsHandler implementations 
Because the proxy.Provider interface included
proxyconfig.EndpointsHandler, all the backends needed to
implement its methods. But iptables, ipvs, and winkernel implemented
them as no-ops, and metaproxier had an implementation that wouldn't
actually work (because it couldn't handle Services with no active
Endpoints).

Since Endpoints processing in kube-proxy is deprecated (and can't be
re-enabled unless you're using a backend that doesn't support
EndpointSlice), remove proxyconfig.EndpointsHandler from the
definition of proxy.Provider and drop all the useless implementations.

954996e231 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

d2bc4d0b2e Use shared informers for proxy endpoints and service configs 
Use shared informers instead of creating local controllers/reflectors
for the proxy's endpoints and service configs. This allows downstream
integrators to pass in preexisting shared informers to save on memory &
cpu usage.

This also enables the cache mutation detector for kube-proxy for those
presubmit jobs that already turn it on.

This signature is more consistent with OnEndpointsUpdate and removes a

6bbf2aaab7 Refactor pkg/proxy/config's ServiceConfigHandler and EndpointsConfigHandler to have different update methods. 
Refactor `pkg/proxy/config`’s ServiceConfigHandler.OnUpdate and
EndpointsConfigHandler.OnUpdate to different method names as they have
different signatures.

This will let the new proxy
(https://github.com/GoogleCloudPlatform/kubernetes/issues/3760)
implement both interfaces.

Since we won’t need a separate loadbalancer structure (load balancing
is handled in the proxy rules), we will simply handle both event types
from the same object.
