Came from a conversation with @Peter the other day: Chrome is now supporting at least part of the Network Information API: http://wicg.github.io/netinfo/. Seems like it can't hurt for us to collect this data if available, worst case we just ignore it.
Previous work: T76814: Capture network performance information from navigator.connection

Change 396279 abandoned by Imarlier:
ext.NavigationTiming: Include Network Information in NavTiming events
Reason:
Going to do something more stripped-down than this.
Change 408538 had a related patch set uploaded (by Imarlier; owner: Imarlier):
[mediawiki/extensions/NavigationTiming@master] ext.NavigationTiming: Add effectiveType from the NetworkInfo API
Patch above handles the simplest case, just collecting the effectiveType (which is kind of an intepretation of the other metrics available via the NetInfo API anyway). We can always extend later if there's a reason to do so.
