Slawek Kaplonski 79e24494bf Set DhcpAgentNotification to be "false" by default
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.

# Enabling DVR deploys additional services to the compute nodes that through
# normal operation will consume memory. The amount required is roughly
# proportional to the number of Neutron routers that will be scheduled to
# that host. It is necessary to reserve memory on the compute nodes to avoid
# memory issues when creating instances that are connected to routed
# networks. The current expected consumption is 50 MB per router in addition
# to the base reserved amount. Deployers should refer to existing
# documentation, release notes, etc. for additional information on estimating
# an appropriate value. The provided value here is based on an estimate of 10
# routers and is an example value *only* and should be reviewed and modified
# if necessary before deploying.
