Chiachang Wang 9aaad19a82 Replace Proxy hidden constants and methods usages
Proxy is a part of incoming connectivity mainline module. The
hidden APIs are no longer available outside the module. These
shared constants and methods are moving to ProxyUtils insdide
net shared lib. Update the corresponding usage in the caller
side.
