  - p/fuel: deploy: Allow non-root deploys

    Fuel@OPNFV's ci/deploy.sh script imposes a hard requirement on
    running as the root user, which can be refactored into a series of
    smaller requirements.

    Instead, relax the check to the ability to run sudo commands
    inside the script, and explicitly add sudo for the package
    installation commands.

    This also adds a requirement for the Jenkins user running the
    deploy to be part of the "kvm" and "libvirtd" groups, so
    libvirt/virsh can manage VMs on the jump server / Jenkins slave.

    See related change in OPNFV Releng repository [1].
