This option is set to true by default in Neutron but it should be
disabled in case when OVN backend is used.
It should be enabled only when "traditional" dhcp agents are used in
Neutron.
As OVN is default Neutron backend in the Tripleo, this patch sets
DhcpAgentNotification option to be False by default and enables it only
when neutron-dhcp-agent is going to be deployed.
