    Add radvd_user config option

    In some deployments, the "neutron" user does not have the permissions
    to modify the kernel interfaces. In those cases the radvd user should
    be defined. This patch introduces a new config option: "radvd_user".

    This config option is the username passed to radvd, used to drop root
    privileges and change user ID to username and group ID to the primary
    group of username. If no user specified (by default is an empty string),
    the user executing the L3 agent will be passed. If "root" specified,
    because radvd is spawned as root, no "username" parameter will be
    passed.
