Use shared informers for proxy endpoints and service configs

Browse Source 
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.
