Versions of chef starting at 17.0.178 do not include the knife gem
so we can't require it unconditionally.
This also modifies load_chef_config to use Chef::WorkstationConfigLoader for chef 12+ instead of Knife::chef_config_dir; this is available in 12+ and avoids having to further split behavior on version such as <12 = knife.locate_config_file, <17 = knife.chef_config_file , 17+ config loader.
