Bug 1041572

Description of problem:
This was seen testing RHS 2.1 AMI, yet we believe it may be generic to all AMIs.

The problem is that performing a yum clean all is impacting something with the rhui-lb yum plugin.  

"yum remove" is broken, until we perform a yum operation that fetches metadata, "yum repolist" is sufficient to restore functionality.
