This commit moves the Fedora Infra Docs SOP originally written in
ReStructuredText into an AsciiDoc file in the Badges docs site:

    https://docs.pagure.org/infra-docs/sysadmin-guide/sops/badges.html

Once this is merged into fedora-badges.git, I will follow up with a PR
to the infra-docs.git repository to point to the new home of the SOP so
there are not multiple sources of truth published at the same time.

Also I tested all of the internal links and validated that they work.
