title: Modify commit message on gerrit after patchset creation?
body: <p>So what I am trying to do is: Add the url, for example (<a href="https://gerrit-server/#/c/7456/" rel="noreferrer">https://gerrit-server/#/c/7456/</a>) into the commit message appearing on gerrit.</p>
  
  <p>What I have tried so far is create a file <code>patchset-created</code> under <code>gerrit_site/hooks/</code> wich is launched when I push a change.</p>
  
  <p>The problem is that i can't locate the commit message file, so i can modify it's content.</p>
  
  <p>I figured since I am trying to insert the url into the commit message, I can t do this by using a hook on my local git repository because there is no way to know what url it is going to be associated to on gerrit, so i thought it may be done by using a hook on gerrit side.</p>
  
  <p>Would appreciate any feed back.</p>
