Suggested GK-MANO Framework API of Y1:

1. instantiation request (with all the info fetched from the catalogues, including a call-back URL for 'instance ready' notification)
2. list current instantiations (per user), with status

Regarding 1.: Why do we need a call-back URL? Does the GK not directly use RabbitMQ to talk to the MANO framework (option a)? With this, we can simply send back a broker message when the service instance is ready and do not need a callback URL. Or should the communication between GK and MANO framework be REST-based (option b)?

a) GK <- (AMQP) -> RabbitMQ Broker <- (AMQP) -> SLM plugin

b) GK <- (HTTP REST) -> GK-Adaptor <- (AMQP) -> RabbitMQ Broker <- (AMQP) -> SLM plugin

Both is doable. Its a design decision.
