title: Retrieve parameters from properties file
body: <p>I have several Jenkins parameterized jobs that uses the same parameters and parameters values.
  When I have to change the default value of one of those parameters, I need to go over all of those jobs and reconfigure them.</p>
  
  <p>A simple solution to this problem would be an option to retrieve all parameters from config file (in the master/ in the workspace) but I could not find a sufficient implementation for that.</p>
  
  <p><strong>I want to be able to feed build with standard Java config file</strong> <em>(in format "key"="value")</em> <strong>and then refer to those parameters like every other parameters during the build.</strong></p>
  
  <p>Do you know of an appropriate solution?</p>
