Enable `docker search` on private docker registry.
The cli interface works similar to other registry related commands:

  docker search foo

... searches for foo on the official hub

  docker search localhost:5000/foo

... does the same for the private reg at localhost:5000

Update openSUSE installation instructions

Out of box, the 'sudo' command on openSUSE does not work similarly to other distros.  In this case, the path to usermod should be explicitly given, since /usr/sbin, where usermod is located, is not on the sudoing user's PATH.  The other sudo commands here should be fine.
