Review Comment:
Currently, we initialize the `clusterMap` (type: `NetworkTopology`) in OM
during startup based on the schema file and the fetched `clusterTree`
information (type: `InnerNode`) from `ScmTopologyClient` (which implements a
background thread responsible for periodic caching and refreshing of this
`clusterTree` obtained from SCM at every ~1 hr interval).
