that is in the non iroinc smart nic case. in the ironic smart nic case with the ovs super agent
which is the only case where there would be multiple hypervisor managed by the same
agent the agent will be remote.

so in the non ironic case it does not need to be a list.
in the smartnic case it might need to be a list but a mapping of bridge or pyshnet wont be unique
and a agent hostname (CONF.host) to hypervior host would be 1:N so its not clear how you would select
form the N RPs if all you know form nova is the binding host which is the service host not hypervior hostname.
