"
scylla_setup is currently broken for OEL. This happens because the
OS detection code checks for RHEL and Fedora. CentOS returns itself
as RHEL, but OEL does not.
"
Fixes#4842.
* 'unbreakable' of github.com:glommer/scylla:
scylla_setup: be nicer about unrecognized OS
scylla_util: recognize OEL as part of the RHEL family
