**Why**
- We have some workflow-like flows in @medusajs/medusa. These should be moved over to the workflows package.
- Inventory Items <> Variant currently assume a 1-1 mapping. There should be support for a many-to-many mapping.
**What**
- PR introduces a feature flag for supporting many-to-many mappings for inventory and variants.
- Deletes legacy transaction handler in @medusajs/medusa.
- Adjusts existing createInventoryItems handler to remove dependency on variant data.
**Unkowns**
~~1. Couldn't find an existing test for the CreateProduct workflow. It should be tested that this still works as expected.~~
2. Have removed transaction managers as we should move to handling consistency through orchestration tooling. Are we ready for that?
**What**
Integration tests to validate the workflow compensation.
Also, fix the transaction state when the workflow is compensating and some steps does not have any compensation
what:
Scopes the errors from the exported workflow to return only invoke errors.
If an error occurs on the invoke level, it'll stop the invoke flow and begin the compensation flow. If another error shows up on the compensate level, it doesn't make sense to throw that error since the user won't be able to do anything about it.
**What**
The listProducts handler should not be specific to the workflow.
Same for the product removal, shouldn't expect an entire DTO but just a collection of object that at least contains the id.
Same principle applied to other product handlers
