### What changes were proposed in this pull request?
1. report the `resourceConsumptionSnapshot` from `storageManager` directly in the worker heartbeat, which does not contain the empty user resource consumption
2. For RESTful API, do not return the empty user resource consumption as well.
### Why are the changes needed?
878a83cfa7/common/src/main/scala/org/apache/celeborn/common/meta/WorkerInfo.scala (L239-L248)
Currently, we never remove the user resource consumption even the sub resource consumptions is empty, and create a `ResourceConsumption(0, 0, 0, 0)` instead.
I am afraid that, the worker will report more and more empty user resource consumption to master, once one of their slots assigned to this worker.

So, I think we just need to report the `resourceConsumptionSnapshot` from `storageManager` directly, which does not contain the empty user resource consumption.
