Review Comment:
> What about adding containerCount into DatanodeDetails, or even better...
we could add a Set of ContainerID into DatanodeDetails?
I don't think we should add either of those extra pieces of info in
`DatanodeDetails`. It contains static information, while container count or
container IDs are dynamically changing. The latter could also grow too large.
