Use the avatar services in the user infobox ETag
Review Request #8567 — Created Dec. 12, 2016 and submitted — Latest diff uploaded
Ther user infobox was previously using the e-mail address of users in
ETag calculation because all avatars were Gravatars, which are based off
e-mail addresses. However, now that we have more avatar services
available, data specific to each service must be used to calculate ETag.
Updated the avatar service configuration for a user and saw that the
infobox returned an uncached response.
