Provide more dependency resolution information during treecompose

[jlebon]

During a treecompose, it would be helpful to be able to determine which packages were pulled as a result of what dependency, much like yum/dnf does. This would allow one to more easily understand where newly added/dropped packages come from in between composes.

i'm not sure if you can get that level of detail from DNF. @ignatenkobrain and I had a conversation about it a while back. he might be able to comment.

[ignatenkobrain]

you can't get this level of information. Probably within DNF 3.0 it will be available ;)

[dustymabe]

what's the timeline for DNF 3.0 ? or was that a joke? :)

[ignatenkobrain]

@dustymabe it was joke, but only partially. There are different plans for DNF at this point and to get this information, hawkey needs to be reworked a lot..

Was playing around with just passing more debug flags to libsolv, but yeah, nothing as clear and concise as what yum provided.

we've had quite a few dnf releases since we last discussed. Maybe something has changed there.
