duplicated root_helper entries in neutron.conf and plugin ini

[Akihiro Motoki]

NEC plugin and Brocade plugin has duplicated "root_helper" config option in neutron.conf and plugin ini files. It is confusing when configuring parameters.

Especially "root_helper" in nec.ini is not commented out and this leads to confusion because even after editing neutron.conf root_helper is still "sudo".

    Remove root_helper config from plugin ini

    As root_helper is defined in neutron.conf, root_helper in plugin ini
    is unnecessary and brings confusion when configuring the parameter.
    This patch updates plugin ini of NEC plugin and Brocade plugin.
