Migration Plugin

1. Sync centos8-baseos repo into Pulp 2
2. Migrate it into Pulp 3
3. Sync centos8-kickstart repo into Pulp 2
4. Migrate again using the same plan as before (migrate content but not centos8-kickstart repository)

Result:

If the repository is part of the migration plan, it successfully migrates. Also if both repositories are available during the first migration it successfully migrates.
