Made classMapWatts a commandLine option where one can enable and disable mapping of watts to powerclasses when accepting offers from Mesos. Removed the schedulers that were created solely for the classMapWatts feature. Retrofitted all schedulers to use the powerClass mapped watts attribute for a task, if classMapWatts has been enabled. Removed unnecessary functions and variables from constants.go. Removed unnecessary functions from utilities/utils.go. Fixed operator precendence issue with takeOffer(...) in some of the schedulers. Added TODO to decouple capping strategies from the schedulers completely. Added TODO to move all the common struct attributes in the schedulers into base.go.
