This one is kinda tricky.

Back in v1, there was an issue in reading the RPM's metadata on the 
server. I forget the specifics, but I believe it had something to do 
with a RHEL5 server unable to read certain newer RPMs.

At the time, the solution was to have the client read the RPM metadata 
under the assumption that if it was doing the upload, presumably it 
could open up the RPM it was uploading.

That behavior has stuck around and is set to be reevaluated in the next 
few months. I had wanted to address it in this yum importer rewrite, but 
we just don't have the resources to dig into it.

So to upload an RPM, you have to look at the RPM headers client-side and 
pass them to the server. The easiest thing to do it point you towards 
the code in our client that does it:
pulp_rpm/src/pulp_rpm/extension/admin/upload/package.py

Like I said, we know this is far from ideal and are going to address it 
in the next few months. It's even more annoying since I don't know the 
exact reason it was done this way in the first place, but I'm pretty 
sure my explanation was close.
