[Libguestfs] [PATCH] templates: Add CentOS Stream 8



This adds CentOS Stream 8 to the set of images that the builder
can use. CentOS Stream 8 is a continuously delivered upstream of
the next RHEL 8.x release. It doesn't have a minor version number.

It appears that my index-fragment has a hash in it, and thus this
commit may need to be amended by the maintainer before merging
into the main repo.

This has been tested by creating a local centosstream-8.xz image
then consuming that image via a local repos.d file and using
virt-builder to build a bootable CentOS Stream 8 image:

     $ cat ~/.config/virt-builder/repos.d/local.conf
     [local]
     uri=file:///data/src/guestfs-tools/builder/templates/index
     $ virt-builder --list | grep stream
     centosstream-8           x86_64     CentOS Stream 8
     $ virt-builder centosstream-8

     [  13.5] Finishing off
                   Output file: centosstream-8.img
                   Output size: 6.0G
                 Output format: raw
