Application Build Flow configuration

[aloubyansky]

Maven build relies on maven plugin parameters to configure phases such as augmentation and native image. However, using AppCreator API outside Maven plugin raises a question of where the configuration comes from in that case and in which form. The current assumption is that it will be in some sort of properties (file, MP config, etc). This issue is about a flexible enough mechanism that would allow to configure the build flow from some sort of properties.
