Review comment:
The client connects to an OM and submits a getServiceList request. If this
OM is not the leader, then the client tries a different OM. This all happens
through _OMFailoverProxyProvider_.
Currently, the _getServiceList_ API is only used to discover the SCM
address. It does not return the list of OMs in the cluster.
But based on which OM serves the getServiceList request, we can presume it
to be the leader. We do not need a new request type.
