Replace raw pointers with smart pointers in update_client::URLRequestPostInterceptor

This is a mechanical change. Understanding ownership of various objects such as interceptors
is difficult in the current implementation, and it is prone to memory leaks and
accessing dangling objects.

There is follow-up work to implement support for pausing such interceptors.
