Description of problem:
The most recent update to python-rsa renamed packages to comply with Fedora's current naming guidelines, but did not handle the rename properly and broke upgrades as described here:

https://bodhi.fedoraproject.org/updates/python-rsa-3.3-3.el6#comment-386120


Version-Release number of selected component (if applicable):
python2-rsa-3.3-3.el6


How reproducible:
Always


Steps to Reproduce:
1. Install an old version of python-rsa
2. Run ``yum upgrade''


Actual results:
python-rsa does not upgrade to the new python2-rsa.


Additional info:
The affected version of the package currently contains the following statement:

    Provides: python-rsa

To handle the upgrade properly you need to add an Obsoletes statement to make yum treat it as an upgrade, and you also need to add a version to the Provides statement to ensure versioned package dependencies continue to be satisfied:

    Provides: python-rsa = %{version}-%{release}
    Obsoletes: python-rsa < 3.3-4

The documentation for that is here:  https://fedoraproject.org/wiki/Packaging:Guidelines#Renaming.2FReplacing_Existing_Packages
