title: Extending artifactory's pypi repos with plugins
body: <p>I am trying to migrate a legacy system to use artifactory. However I have two blockers: </p>
  
  <ol> 
  <li> the old scripts require PyPixmlrpc, which artifactory doesn't support 
  <li> they also make use of upload_docs, not supported by artifactory's pypi implementation either
  <li> a smaller issue, the old scripts call register and they expect 200 instead of 204 http status code.
  </ol> 
  
  <p>Would it be possible for me to write a plugin to implement this? </p>
  
  <p>Looking at <a href="https://www.jfrog.com/confluence/display/RTF/User+Plugins" rel="nofollow noreferrer">https://www.jfrog.com/confluence/display/RTF/User+Plugins</a> I couldn't find a callback for when <code>POST /api/pypi/&lt;index-name&gt;</code> is requested. </p>
  
  <p>If I can make 
  <ol> 
  <li> work for the methods we actually use, <li> to just pretend it deployed docs and <li> to respond with the correct status code  </ol> I will be happy enough.</p>
