Move all dependency tracking to an external class which simplifies the relationships and allows managing Trove without necessarily using packages. This change also cleans up how the client is handled to make it more configurable and match other modules. Finally the reference to the deprecated and non-functional keystone::python class is dropped. Change-Id: I943685fbeb114dead80b7465b8f5c564a0bc9fe0
