Log captive portal status when an SSL interstitial is displayed.
When an SSL interstitial is displayed, we want to understand whether it's potentially caused by a captive portal or not. This CL records the following flags when the interstitial is closed:
1) Whether captive portal detection is enabled in Chrome (disabled on some OS).
2) Whether a captive portal probe result was received.
3) Whether the captive portal probe result returned no response, indicating a network or HTTP error or a non-HTTP captive portal login page.
4) Whether a captive portal was detected.
