standard-test-scripts: Ansible role for executing test scripts
    
    Put this role in your tests.yml playbook and specify a
    number of test scripts to execute as tests. The results
    of each script will be piped into log file in the artifacts
    directory. If any script exits with a non-zero exit code
    the role will fail.
    
    In the case of test subjects such a host or container, these
    test scripts and related files will be copied to the target into
    /var/tmp/tests before execution.
    
    You should define the following variables:
    
     * tests: An array of scripts to run
     * files: A list of files or directories needed by the scripts
