[tor-commits] [stem/master] Rename new authentication methods



commit e302e46be576afac28bb84f5c6865047cd7fdf68
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>

    Rename new authentication methods
    
    These method names were based on the controller commands which is fine, but we
    have some conventions of our own. Renaming these methods for a couple
    reasons...
    
      * For consitency Stem still calls these 'hidden services', and will continue
        to do so until...
    
        https://trac.torproject.org/projects/tor/ticket/25918
    
      * We prefix getter methods like this with 'list_'.
