[Discuss OpenCPI] OpenCPI 1.5 Install Failure

Hmm.  The baseurl for yum specifies the directory containing 
the repodata folder. Yum does a download 
for baseurl/repodata/repomd.xml.  We tested the new repo file by doing a 
yum makecahe and it worked, so we're still thinking github or centos7 
repo was having issues. Here is a transcript of our latest experiment, 
following the 3 commands in the top-level README of our repo.  As you 
can see even the centos epel repo failed and used another mirror.  
Perhaps we should recommend "yum makecache"  to make it clear the 
difference between a repo failure and an installation failure.
