Migration Plugin

All the metadata is parsed in pulp 2 , so everyting can be take from the db.

The main part of this task is to figure out how to separate errata package lists so one erratum in pulp 2 will end up into N advisories in pulp 3. And then which advisory to assign to which repo.

Proposal¶

Extend Pulp2 model to track information about pulp2 repositories an erratum belongs to. Process errata in a similar way it happens in Pulp 2 during publish. In the viewset for this model provide a repo version this erratum was migrated to.
