title: Jenkins to pick a random value from available options
body: <p>I am running a Jenkins job to create data for test-users . </p>
  
  <p>Now, I need it to pick a random value from the list of users when I generate the data. Right now the job runs daily and pumps data to a specific user set as a default. I have a String parameter that takes this value.</p>
  
  <p>Is it possible to make it pick a random value from a list of say 5 users, so that I have multiple users with similar kind of data.</p>
