      Removed pre-emption from capacity scheduler. The impact of this change is that capacities for queues can no longer be guaranteed within a given span of time. Also changed configuration variables to remove pre-emption related variables and better reflect the absence of guarantees.

      Description

      In an effort to simplify the code base, we would like to remove the pre-emption related code in the capacity scheduler. We would reintroduce this (possibly with some revisions to the original design) after a while. This will be an incompatible change. Any objections ?
