          Issue Type: Improvement
          Components: capacityscheduler, resourcemanager
    Affects Versions: 3.0.0-alpha2, 2.8.1
            Reporter: Roni Burd

Resource object is used multiple due to ResourceCalculator creates new instances on every method call. This gets called several times on each node HB. Resource is a very expensive object that relies on Protobufs 

The change is to remove the need to use protobuf on the Resource object and avoid creating many objects in the Resource Calculator all the time
