The 'yum makecache' step is failing. The issue is seen when the fast
mirror plugin for yum is in use (default).
The metadata for a yum repo as scattered across several files. The
master file is repomd.xml, and it may list several supporting files,
e.g.
filelists.xml.gz
primary.xml.gz
filelists.sqlite.bz2
other.sqlite.bz2
other.xml.gz
primary.sqlite.bz2
When fast mirror plugin is in use, each file might download from a
separate source. This opens the door for a race condition when a repo
update is rolling out across the mirrors.
The error suggests we have already downloaded a repomd.xml, but it is
obsolete and references a supporting file that no longer exists.
A second possible source of inconsistent data is caching proxies.
Solution:
1) Disabling the yum fast cache plugin is undesirable, and there
is no option forcing metadata iof a given repo to be single sourced.
So this update adds a limited number of retries for the
'yum makecache' command.
So far we've never seen 'yum makecache' fail twice in a row...
largely because the 'fastest mirror' plugin rarely downloaded from the
same source twice.
2) Add 'http_caching=packages' to yum.conf, which asks upstream proxies
to not cache repodata.

This uses the local yum.repos.d and sets the releasever=7 needed
for running on a non-yum based machine.
