As a user, I would like to see the input form pre-filled up when appropriate so that my experience is simplified. 

Scenarios where this feature will be applied:

• I would like to click in a suggested infrastructure workflow after running the assessment workflow and see the form pre-filled up with all properties that I have provided in the assessment workflow. Pre-filled-up fields will be disabled. (FLPATH-858)
• I would like to restart a failed/completed workflow without providing all the input values again. Pre-filled-up fields can still be editable. (FLPATH-882)

Thus, we need an endpoint that would take care of extracting the inputs that have been provided in a given instance, respecting the schema structure.

The response must also follow the schema structure.

To be able to cover both scenarios, this endpoint would need to receive the `instanceId` and the `workflowId`.

• For the assessment use case: `instanceId` of the assessment workflow run and `workflowId` of the chosen infrastructure workflow
• For restarting workflows: `instanceId` of the previous run and `workflowId` of the same workflow (in this case, maybe `workflowId` could be omitted)
