Yeah, there's work under way to allow custom placement of services, but
for the moment it would probably need to run on the controllers.

Assuming the service supports this, it should be doable.

It's possible, but to my knowledge there isn't any existing support for
LBaaS in TripleO.  To enable it, you would need to:

-Add it to the TripleO loadbalancer puppet manifest:
https://github.com/openstack/puppet-tripleo/blob/master/manifests/loadbalancer.pp
-Add the necessary hieradata to enable it in tripleo-heat-templates.

This is assuming there is existing puppet support for it.  If not, there
would be some additional steps to get that into the puppet modules we use.
