Merged into purchase_stock (receipt_status field)

Please @pedrobaeza can you review it?

Shouldn't there be a migration script renaming the column and mapping the option values to the former ones?

Interesting, but I'm not sure if doing so is the best thing to do (case of all cancelled pickings) OCA/purchase-workflow#2081 (comment)

I think we can plan it this way:

• Add the merge in apriori as it is here.
• Add in the purchase_stock migration scripts that if we find the old column from this module, copy it with the name, and transform values. Cancelled status is passed to NULL, as stated in my comment on the PR.
• Still on purchase_stock, if we don't find the column, we pre-create it and fill it according the rules of the computed field.

I'm going to speed up purchase migration scripts PR for merging it, so that we add the purchase_stock ones.
