    Add root_helper to quantum agents.

    When running commands that require root privileges, the linuxbridge,
    openvswitch, and ryu agent now prepend the commands with the value of
    the root_helper config variable. This is set to "sudo" in the plugins'
    .ini files, allowing the agent to run as a non-root user with
    appropriate sudo privilidges.

    If root_helper is changed to "sudo quantum-rootwrap",
    then the command being run will be filtered against lists of each
    agent's valid commands in quantum/rootwrap. See
    http://wiki.openstack.org/Packager/Rootwrap for details.

    Fixes bug 948467.
