This patch contains the base class for Rally benchmark scenarios for Nova. The class provides several helper methods for booting/suspending servers and images. These methods will be of great use in the actual benchmark scenarios for Nova servers, floating_ips, metadata enrties etc. Blueprint benchmark-scenarios Change-Id: I29301d6ee1b1cca2939004acf3d681b01f101b44
