Using `git grep el6` and `git grep el7` and variants like EL-7 or
el-7, I found various entries and files which were no longer needed
with the current ansible. I updated text or tests to later versions of
RHEL as needed.
found entries for the fedora ami's for the original cloud and removed
those entries also.
