[Review] Request from 'aduffeck' @ 'SUSE/machinery/review_140728_fix_integration_tests'

Please review the following changes:
  * fec305c More adaptions to new repository structure
  * b9d1f1a Generate a SSH identity so that we can ssh into other machines
Are you sure that ssh-keygen doesn't create the directory? RSA should also be the default and the name id_rsa too.
