PSA: Improvements to metrics UI on chromestatus.com

[Jason Robbins]

FYI, this week there are two improvements to the display of metrics on chromestatus.com.

1. Thanks to Chris Harrelson and Barry Pollard, the set of sample URLs from HTTP Archive is now sorted by rank. E.g., https://chromestatus.com/metrics/feature/timeline/popularity/973

2. Our Google Summer of Code contributor, Pingren Nie, has started the summer off early by hiding "OBSOLETE_" metrics from the list of metrics, unless you uncheck a checkbox to indicate that you want to see them.  E.g., https://chromestatus.com/metrics/feature/popularity

Thanks,

jason!
