Upload support

[bowlofeggs]

This pull request introduces upload support. It does not come with documentation, as that will be part of a later pull request. If you wish to test uploading an archive: find any Python package, and run it's setup.py with the sdist argument. It will output a tarball, and you should be able to upload that to Pulp. To verify that it's been uploaded, you should be able to see it in Mongo like this:

> db.units_python_package.find()

Also, you should find the package you uploaded stored in /var/lib/pulp/content/python_package/.

All tests pass for me on FC20

The upload worked! Here is the metadata I see in the DB:

I expected this to be for 'filename' not 'args'. Also the filename field should be documented.

[bowlofeggs]

This was supposed to say filename - I'll fix it.

[bowlofeggs]

Fixed.
