Review comment:
What is the use case for this RPC? it is used only from the OM HA tool? or
is some thing that clients need to know when communicating with the OM? if
clients need to know this info, then clients already make a call called
getServiceList and this info is more appropriate to be part of that call? Then
both clients and tools like OM HA can get to that information pretty easily.
