hosts.update: Reconfigure CentOS 8 repositories to vault

CentOS Stream 8 reached EOL but our GPFS and GlusterFS environment
setup still has some dependencies which are not yet fulfilled by
CentOS Stream 9. In case of GlusterFS it lacks few gluster-ansible
related rpms whereas GPFS is not yet ready to be compiled against
newer kernel versions from CentOS Stream 9.

Therefore we stick to CentOS Stream 8 till requirements are met.
See samba-in-kubernetes#102
for further developments.
