In this changeset, I changed the Strategy base class to add new abstract class methods. I also added an abstract strategy class per Goal type (dummy, server consolidation, thermal optimization). This changeset also includes an update of the /goals Watcher API endpoint to now use the new Goal model (DB entries) instead of reading from the configuration file. Partially Implements: blueprint get-goal-from-strategy Change-Id: Iecfed58c72f3f9df4e9d27e50a3a274a1fc0a75f
