title: Change owner of a Gerrit change
body: <p>I am creating an auto-integrate script which takes in changes and source and destination branches. </p>
  
  <p>The problem is that once its pushed to Gerrit the owner is me. </p>
  
  <p>I want to change it to the author or committer. </p>
  
  <p>Is it possible to change the owner to someone else? </p>
  
  <p>If not, is it possible to give abandon, Topic etc rights to the committer for a change. The reason I want to change the Gerrit owner is to give the authors/committers access to abandon etc.</p>
