Neutron configuration changes

dnsmasq rootwrap filter

The rootwrap filter for the Neutron dhcp agent needs updating in Kilo. In /usr/share/neutron/rootwrap/dhcp.filters, replace any lines starting with dnsmasq:, for example:

dnsmasq: EnvFilter, env, root, CONFIG_FILE=, NETWORK_ID=, dnsmasq

With:

dnsmasq: CommandFilter, dnsmasq, root
