Easiser to switch to the requests package than to figure out how to deal
with some of the encoding changes manually. And as a bonus, it's much
nicer to work with the requests package for the future.
The code was supposed to pick the latest version of the repo rpm in this
scenario, but at some point the data structure was updated and the code
was not, so it ended up actually picking the *oldest* version of the
repo rpm.
We do this by always spidering every repo rpm available (since the ftp
server doesn't know about supported versions), and then filtering which
versions are shown in the dropdown instead. Given the small number of
versions of either kind, this doesn't make a material difference in the
size of the files anyway.
The ftp server can then submit a list (and structure) of which platforms
are supported for yum downloads, which can then later (in a separate
commit) be used to generate a nicer download for yum repo rpms.
