Load upgrade modules
Upgrade modules are loaded using pluginutils. The pluginutils module
is either loaded from site-packages via normal or via a user-loaded
module supplied in the __init__ method. This is useful when the engine
is running before actually being installed into site-packages.
@param remove_applied: if True, already applied upgrades will not
be included, if False the entire upgrade graph will be
returned.
