We have a situation where a set of non-osgi components must be installed
in a specific order (leaf first when looking at the dependency tree). Is
there any way to tell p2 to call touchpoints in a specific order?
A depends on B which depends on C. I tell p2 to install A which of
course means it also downloads B and C. Once the resolve and download is
complete it's essential that C is installed first, then B and lastly A.
