Merge pull request #71573 from JacobTanenbaum/UDP_conntrack 
Correctly Clear conntrack entry on endpoint changes when using nodeport

Jacob Tanenbaum 144280e7a7 Correctly Clear conntrack entrty on endpoint changes when using nodeport 
When using NodePort to connect to an endpoint using UDP, if the endpoint is deleted on
restoration of the endpoint traffic does not flow. This happens because conntrack holds
the state of the connection and the proxy does not correctly clear the conntrack entry
for the stale endpoint.

Introduced a new function to conntrack ClearEntriesForPortNAT that uses the endpointIP
and NodePort to remove the stale conntrack entry and allow traffic to resume when
the endpoint is restored.

Laurent Bernaille ed65f6edeb [kube-proxy/ipvs] Handle UDP graceful termination 
The current logic is to delete a RS if the number of active connections
is 0. This makes sense for TCP but for UDP the number of active
connections is always 0. This is an issue for DNS queries because the RS
will be deleted but the IPVS connection will remain until it expires
(5mn by default) and if there are a lot of DNS queries, the port will be
reused and queries blackholed. Of course for this to work properly the
service needs to continue to serve queries until the connections expire
(this works fine with the lameduck option of coredns).

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

flush iptable chains first and then remove them 
while cleaning up ipvs mode. flushing iptable chains first and then
remove the chains. this avoids trying to remove chains that are still
referenced by rules in other chains.
