  - functest: Move run-functest.sh execution out of ansible

    Ansible throws out the log at the end of task execution which
    makes it hard to read. This change renames the role to prepare-functest
    and then takes the script execution out which will be executed by
    releng/jjb/xci/xci-run-functest.sh.
