AbstractImageBundler
This is the base class for each of the Application Image Bundlers.
It contains methods and parameters common to all Image Bundlers.
Application Image Bundlers are created in "create-app-image" mode,
or as an intermediate step in "create-installer" mode.
The concrete implementations are in the platform specific Bundlers.
