[kube-proxy] add log verbosity to endpoint topology hint loop.

We enabled topology hint on one of our services and this log line was
emitted ~92 million times in one day from one cluster tripping our log
quota for that cluster, as it is the log line cannot be disabled via the
`-v` flag because it does not specify verbosity.

I think more log locations need to set verbosity at which they are
logged, but this one is currently hurting the most.
