[ANT-706] Add renewables clusters API endpoints

[hdinia]

Problem Statement

To work with the new UI we need to implement new RESTful API endpoints that provide CRUD functionality for renewable clusters within a given study's area. The endpoints will be nested under each area, allowing for direct manipulation of the renewable clusters related to that specific area.

Proposed Solution

Add API endpoints so users can:
Users can create new renewable clusters within an area.
Users can retrieve all renewable clusters within an area.
Users can update information for an existing renewable cluster.
Users can delete a renewable cluster within an area.

• The desired outcome

API Endpoints to Implement:
POST /studies/{uuid}/areas/{area_id}/clusters/renewable - Create a new renewable cluster.
GET /studies/{uuid}/areas/{area_id}/clusters/renewable - Retrieve all renewable clusters in an area.
GET /studies/{uuid}/areas/{area_id}/clusters/renewable/{cluster_id}- Retrieve a specific renewable cluster.
PUT /studies/{uuid}/areas/{area_id}/clusters/renewable/{cluster_id} - Update a specific renewable cluster.
DELETE /studies/{uuid}/areas/{area_id}/clusters/renewable/{cluster_id} - Delete a specific renewable cluster.
