[CentOS] Missing repodata/ for CentOS 8 on

Hi folks,

I've noted that the CentOS 8 debuginfo repo lacks the repodata/ directory:

    http://debuginfo.centos.org/8/x86_64/

Did the maintainers forget to upload it? It does have all the .rpm
files under the Packages/ sub-directory though:

    http://debuginfo.centos.org/8/x86_64/Packages/

And no repodata/ there either.

Also, I've noted the 8-stream/ directory which is empty. Is it
something we are supposed to use too?

Thanks for your help!

Best,
Yichun
