    freshmaker-cli: Use "dep_on_id" to generate the tree, fix the prod/stage links.
    
    To be able to change the rebuilt_nvr when build fails for unknown reason,
    we need to stop relying on rebuilt_nvr in the freshmaker-cli and instead
    use the dep_on_id.
    
    This commit changes the code to construct the tree based on the images
    dependencies to use the dep_on_id. It also documents the way how this
    code works and rationalise it a bit.
