If you plan to use haproxy namespace driver, then you should install
'haproxy' package yourself. As for 'openstack-neutron-lbaas' package, I
believe it should be installed on both controller as well as network nodes.

This should be safe to apply. It will create some new tables in the neutron
database for LBaaS service plugin to use.
