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.
