Add CentOS 8 support for rpm deployment

We were only supporting CentOS 8 for containerized deployment.
Since Nautilus 14.2.10 we now have el8 rpm packages so we should be
able to deploy a nautilus ceph cluster with el8.
Note that the nfs-ganesha isn't supported because there's no el8 rpm
packages for nfs-ganesha V2.8.
