AppStream kickstart repos were missing from the initial collection
of repos used to test the kickstart repo index functionality. AppStream
repos uniquely do not contain "checksums" sections in their treeinfo
files. So, when attempting to run repo-autoindex against an AppStream
kickstart repo, "KeyError: 'checksums'" was raised.
Now, when encountering an AppStream kickstart repo, repo-autoindex
does not attempt to parse the "checksums" section.
Due to the presence of a "repodata/repomd.xml" path in a kickstart
repo, repo-autoindex previously interpreted kickstart repos as yum
repos. As such, a kickstart repo's index would solely consist of two
directories: "Packages" and "repodata".
While a kickstart repo does contain a yum repo, kickstart repos also
contain two additional repo entry points: treeinfo and extra_files.json.
Each entry point references additional files that should be included
in a kickstart repo's index. These files were previously ignored.
Now, when repo-autoindex encounters a kickstart repo, repo-autoindex
produces a repo index that reflects the content referenced in all
three repo entry points (repomd.xml, treeinfo, extra_files.json).
