Added HostResolveImpl Requests and Jobs to log.

ConnectJobs point to the requests, Requests point back to ConnectJobs and to the DNS lookup they were attached to, if any.

Also CONNECT_JOBs are now identified by their host/port on the Requests list.


BUG= 46844
TEST= Look at the net-internals screen.
