Leverage profile's http network session HttpAuthCache to support proxy auth.

This allows the connect job to leverage any auth cache credentials the profile
has, including those the user gets prompted for as part of loading a page
while behind an authenticated proxy. GCM continues to use its own network
session for creating the connections, but at connection time the HttpAuthCache
is coped over from the profile's http network session (if available).
