It is not possible to make operations related to the routes with the API

[Senyoret1]

Describe the bug
The hypervisor API has various endpoints that allow to work with the routes, like GET /nodes/{pk}/routes/{rid}. The problem is that it is not possible to get the value that must be sent as the {rid} param, as the hypervisor API does not have an endpoint for getting the ID of the routes.

Calling the GET /nodes/{pk}/routes endpoint only returns a key property for each route, which worked before when sent as the {rid} param, but not anymore, as the API responds error: "invalid UUID length: 0".

Possible implementation
2 possible solutions are:

• Add the ID to the GET /nodes/{pk}/routes endpoint.
• Make the API endpoints related to the routes work if the key property returned by the GET /nodes/{pk}/routes endpoint is sent as the {rid} param.
