We now have an initial/preliminary obscore configuration for embargo repo, so we can go ahead with adding obscore table based on that. Actual job is done using migration scripts in daf_butler_migrate to create the table and butler command in dax_obscore to populate that with pre-existing data.

I want to test this on a copy of embargo repo to make sure (once more) that migration scripts work OK. I also think that migration scripts were written for namespace=oga, and new config uses namespace=embargo (I think embargo is better choice), so likely I'll need to update migration scripts as well.
