Constants that are used across scripts
1. The available hosts = stratos-00x (x varies from 1 to 8)
<<<<<<< HEAD
2. CapMargin = percentage of the requested power to allocate
3. ConsiderationWindowSize = number of tasks to consider for computation of the dynamic cap.

2. cap_margin = percentage of the requested power to allocate
3. power_threshold = overloading factor
5. window_size = number of tasks to consider for computation of the dynamic cap.

Also, exposing functions to update or initialize some of the constants.

TODO: Clean this up and use Mesos Attributes instead.
