[rawhide] python3, selinux policycoreutils-python, and cloud-init

[Matthew Miller]

Because Python is not small, I would really like to avoid pulling Python 3
into the base cloud image until we can move Python 2 out. (Ideally, I'd like
to move Python out _entirely_, but that's a long, long path. )

It looks like policycoreutils-python in Rawhide is now Python 3. Cloud-init
pulls this in because when it moves things around or creates files, it then
runs selinux.restorecon on them.

I don't _really_ want to say that policycoreutils-python should go back to
Python 2, but I don't think everything else is in the cloud image going to
be ready for F21. See the change coordination page for Python3 at
https://fedoraproject.org/wiki/Changes/Python_3_as_Default)

What are the options here? A python 2 module in parallel? Execing
/sbin/restorecon instead of using the bindings? Refactoring the code so that
running restorecon all the time isn't necessary?
