title: Gerrit REST API, get user activity
body: <p>I'm trying to monitor user commit activity (initial change commit or patching) in Gerrit using REST API.</p>
  
  <p>Right now I have a working example that gets all changes per user using:<strong>"changes/?q=owner:"</strong> and lists one change for each user based on the latest change created date. The problem is that this method misses two things:</p>
  
  <ol>
  <li>If a user commits a patch on a change created by the user itself, but on a different date compared to created date, this activity will not be caught.</li>
  <li>If a user commits a patch on a change created by another user, this activity will not be caught. Worst case for this is that we have a user that never commits any own new initial changes, just working with patching other users initial changes.</li>
  </ol>
  
  <p>Instead I would like to create a query in Gerrit like “give me all activities for user joe” and the look through the result for latest initial commit or patch activity.</p>
  
  <p>Can this be done?</p>
