Replace usages of SdkAware in sdk module with Module

Previously, the sdk snapshot code used SdkAware instead of Module to
ensure that all its members had implemented SdkAware. However, it never
used any of the methods provided by SdkAware, or if it did it no longer
does. So, this change replaces usages of SdkAware with Module in
preparation for deleting it completely.
