Adds Neutron LBaaS Support

Previously, kolla did not support neutron lbaas functionality.
Only Lbaasv2 is supported in Mitaka. Additional information can
be found here:
http://docs.openstack.org/mitaka/networking-guide/adv-config-lbaas.html
Magnum uses Neutron Lbaas to provide high availability to COE API
and Etcd endpoints within a bay. Therefore, Neutron Lbaas is required
for Kolla to support Magnum.
