Install RDO release RPM without GPG checks
Install RDO release RPM without GPG checks

The RDO release RPM isn't signed, but all of the repositories it
configures have GPG signing enabled. Although CentOS normally doesn't
check GPG signatures for packages that are installed locally, the
security role enables those checks for all local packages.
