[WebRTC] Copy HttpAuthCache from main request context into webrtc context
WebRTC uses ProxyResolvingClientSocket to tunnel through proxies. The
socket creates a new request context using a provided request context as
a base. This CL changes this logic to copy the HttpAuthCache from the
original request context to the next context so that proxies that
require explict credentials can be used.
