Goal:

Create a new experimental compose endpoint for Bootc ( e.g /experimental/compose) integration that enqueues a new compose request with an updated image request payload. Introduce a new imageRef and remove other mandatory fields like repositories to simplify the process and prevent breaking existing functionalities.

Acceptance Criteria:

• Verify that the endpoint starts a compose request, returns valid compose ID, similar to a regular compose request
• Verify that the new experimental endpoint accepts compose requests specifically for Bootc integration.
• Verify that the updated image request payload with the new imageRef functions as intended.
• Ensure that the introduction of the new endpoint does not disrupt existing endpoints.
