We should log UMA metrics for Websocket and Form submission autoupgrades, and UKM for subresource upgrades, they should log failure/success, and in the fallback case, delay.
Requesting merge approval into 71 since we'd like to gather initial metrics from there. CL above (which is in canary now) adds UMA metrics (which I've checked via chrome://histograms) that are only logged when the "AutoupgradeMixedContent" feature flag is enabled.
This bug requires manual review: DEPS changes referenced in bugdroid comments.
