I don't think source tracking is that important in this case scenario.

relayd will only have one host, which will be the dnsdist listening on 
localhost (on each load balancer).

dnsdist will have whatever it can support with stickiness/source-tracking.

pf rdr-to could also be an option, but then you loose the carp demotion which 
relayd provides.
