Backend UI API Wrapper: Create Contract Definition Endpoint with 0.2.x

[efiege]

Feature Request

Description

Dealing with JSON-LD in Angular templates does not work, so before we add an intermediate layer into our UI we want to deal with the JSON-LD in our UI API Wrapper. Thus we want to add a new endpoint to type safely use the EDC Version 0 APIs from our UI.

Note that the in operator has not been working in version 0.1.2, but this issue has already been fixed:
eclipse-edc/Connector#3216

Here is a comparison of the old and the new request:

Solution Proposal and Work Breakdown

• Pass @context for edc
• rename id to @id
• Pass "@type": "ContractDefinition"
• replace criteria with edc:assetsSelector
