Migration Plugin

I synced rhel 8 os and appstream and for whatever reason, none of the yum metadata files are migrated:

# select * from pulp_2to3_migration_pulp2yumrepometadatafile;
 pulp_id | pulp_created | pulp_last_updated | data_type | checksum | checksum_type | repo_id | pulp2content_id 
---------+--------------+-------------------+-----------+----------+---------------+---------+-----------------
(0 rows)

pulpcore=# select * from rpm_repometadatafile;
 content_ptr_id | data_type | checksum_type | checksum 
----------------+-----------+---------------+----------
(0 rows)

steps to reproduce:

1. sync rhel8 base os or appstream (i'm guessing any will do)
2. try to migrate the repository, i imagine a simple migration plan should work.
3. No yum metadata files are migrated

No errors were seen
