### What should this feature add?

It would be great to have API endpoint to add specific workflow (by ID of saved workflow, or by workflow JSON) to queue, instead of always providing generated `graph` i.e. calling `enqueue_batch` without `graph` but only `workflow` and `data` fields.

This is very useful for creating custom API users that use workflows that could be changed anytime.
