It's not clear for me how this commit is supposed to bring rpmUtils and createrepo python libraries and even if there is something in docs which may bring those python libs as dependencies why no list those dependencies for python package explicitly?

[Ivan (ibogomazov)]

There is no rpmUtils and createrepo in python pypi. That's why we install them with system packages.

[Sergey Yudin (tsipa740)]

Im not sure where you installing rpmutils and createrepo but i think that would be good idea to

1) write it out onto documentation https://github.com/openstack/packetary/blob/master/doc/source/installation.rst

2) do not import rpmutils and do not trow error when rpmutils is not used
