title: Get the list of user variables from Octopus
body: <p>we have Octopus-2.0.
  We stored the service credentials (they are per machine) in octopus user variable.
  I need to create these login in SQL server as well. </p>
  
  <p>For Example service login name "machine1_service1" stored as variable name. and password of that login is stored under column Variable Value in octopus.</p>
  
  <p>so far i know that to any variable value from octopus we need to provide exact variable name. but in this case I actually need to get list of all these variables.</p>
  
  <p>Is there a way to accomplish this?</p>
