    Add instruction on enable autoupdate in RHEL 8
    
    The tool for auto upgrade is changed from `yum-cron` to `dnf-automatic` in RHEL 8/ CentOS 8/ Fedora22.
    
    A session on how to setup `dnf-automatic` in RHEL 8/ CentOS 8 is added, which is based on https://fedoraproject.org/wiki/AutoUpdates#Fedora_22_or_later_versions
