Python Support

I created a python repo and uploaded a single pip to it.

I then put that content into a repository which worked, and I think tried to create a publicaiton:

$ http post $pulp/pulp/api/v3/publications/python/pypi/ repository=/pulp/api/v3/repositories/6c635fe8-616d-41d9-b69b-27c682dbe6b9/

but the resulting task failed with:

"description": "[Errno 36] File name too long: \"simple/[{'name': 'development status :: 3 - alpha'}, {'name': 'intended audience :: developers'}, {'name': 'topic :: software development :: libraries :: python modules'}, {'name': 'license :: osi approved :: mit license'}, {'name': 'programming language :: python :: 2'}, {'name': 'programming language :: python :: 2-6'}, {'name': 'programming language :: python :: 2-7'}, {'name': 'programming language :: python :: 3'}, {'name': 'programming language :: python :: 3-3'}, {'name': 'programming language :: python :: 3-4'}, {'name': 'programming language :: python :: 3-5'}, {'name': 'programming language :: python :: 3-6'}]/\"",

    },

Further, if I use `repository_version` instead, the task fails the same way.
