Description

Currently, if ozone.om.service.ids is defined but either ozone.om.nodes.<serviceID> or ozone.om.address<serviceID>.<nodeID> keys are not defined, then OM throws OzoneIllegalArgumentException. 

For a single node OM cluster, we should always fallback to ozone.om.address (even if service id is defined).
