Reland 54771 (and 54795) To enable TCP Preconnection by default
I pulled out the code to update the socket connectivity stats.
I added defensive code which should preclude the crash that
was reported on the stability bot.
I added a second call to update the stats from
~ClientSocketHandle to ensure that we updated the
related ClientSocket when we are torn down.
As noted in the original checkin:
Enable speculative preconnection by default
Added histogram to track preconnection utilization (vs waste).
