[Pulp-list] Migration failure, 2.16 -> 2.18

[Kodiak Firesmith]

Thanks very much for this lead.  This is probably something that will be
good for everyone to know about as RHEL 8 beta includes modular
repositories.  In my case, the only modular yum metadata was RHEL 8 and was
in fact a gzip file (so sayeth the 'file' command and from head $file it
appeared to be binary).

I went ahead and traversed
/var/lib/pulp/content/units/yum_repo_metadata_file -type f -name *.gz, fed
them into the file command, and they all came back as compressed files.

Should I run 'find' in any other paths by chance?  Any other .gz files seem
to be symlinks back to the file in /var/lib/pulp/content/units :(

Thanks!
