c0392d72e9 enforce the interface relationship between ServicePort and BaseServiceInfo 
Currently the BaseServiceInfo struct implements the ServicePort interface, but
only uses that interface sometimes. All the elements of BaseServiceInfo are exported
and sometimes the interface is used to access them and othertimes not

I extended the ServicePort interface so that all relevent values can be accessed through
it and unexported all the elements of BaseServiceInfo

017f57a6b0 proxy: add some useful metrics 
This adds some useful metrics around pending changes and last successful
sync time.

The goal is for administrators to be able to alert on proxies that, for
whatever reason, are quite stale.

c3548165d5 Clear conntrack entries on 0 -> 1 endpoint transition with externalIPs 
As part of the endpoint creation process when going from 0 -> 1 conntrack entries
are cleared. This is to prevent an existing conntrack entry from preventing traffic
to the service. Currently the system ignores the existance of the services external IP
addresses, which exposes that errant behavior

This adds the externalIP addresses of udp services to the list of conntrack entries that
get cleared. Allowing traffic to flow

168602e597 Clear conntrack entries for externalIP 
When an endpoint is deleted, the conntrack entries are cleared for
clusterIP but not for externalIP of the service. This change adds
that step.

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
