Restore the functionality that was removed in r9928. This lets the load

balancer plugin work again. Create a new method, GetClientEP, to retrieve
only the EndPoint for script usage. Marked the purpose of the method
in IClientAPI.cs with a warning. Also restored the corresponding SetClientInfo
functionality.
