Query DNS for HTTPS records (alongside traditional A and AAAA queries). When a website has deployed an HTTPS DNS record and Chrome receives it, Chrome will always connect to the website via HTTPS. Design doc for all Chrome DNS HTTPS plans: https://docs.google.com/document/d/1k461sRbddjDGj7Q8f-ZKHZvmB-ENUWSdX_3Fpp2dmXQ This feature covers just the basic query and HTTP->HTTPS upgrade part of those plans, and only for simpler cases that do not require followup DNS queries by the Chrome DNS stack.
