title: CVS repository missing connection types
body: <p>I'm new to using CVS repositories. I'm trying to import a repo by right clicking in the CVS repositories area, New -> Repository Location and then a window pops up with Add CVS repository. Under connection type, in Eclipse Luna I have 'extssh', but in Eclipse Mars I only have 'ext' and 'pserver'.</p>
  
  <p>I need to use extssh. What is it and how do I configure it?</p>
