[tor-commits] [tor/master] prop224: Move service version into config object



commit 5d64ceb12defdc7db8402088fb2946c35274636a
Author: David Goulet <dgoulet@xxxxxxxxxxxxxx>
Date:   Thu Jul 13 08:51:14 2017 -0400

    prop224: Move service version into config object
    
    It makes more sense to have the version in the configuration object of the
    service because it is afterall a torrc option (HiddenServiceVersion).
