Analytics/Commit Guidelines

Commit summary guidelines for Analytics

 * Follow https://www.mediawiki.org/wiki/Git/Commit_message_guidelines
 * In case of a Feature or Infrastructure Task add the Mingle reference on a separate line like:
 * analytics card 42.1
 * analytics card #42.1
 * analytics-card 42.1
 * analytics-card #42.1
 * Card: analytics 42.1
 * Card: analytics-42.1
 * Card:analytics#42.1
 * 42 refers to the Mingle card while 1 refers to the User Acceptance Criteria (in case of a Feature) or the Task (in case of an Infrastructure Task).
 * In case your commit fixes a bug then please add both the Mingle card id and the bugzilla id on a separate line. Adding the bug reference will trigger the bugzilla-gerrit bot and add a link to the patchset in Bugzilla.
 * Bug: 12345
 * Make sure you push to Gerrit.
 * If it is not obvious how to test your commit (eg you have to do magic things to your set up in order to test), explain it in the commit message.
