scale(quantity, conf)

@callback scale(quantity(), conf()) :: {:ok, conf()} | {:error, term()}

Called to horizontally scale a cloud resource up or down.

Successful scaling requests must return a new conf to be used during the next call to scale/2. That allows cloud modules to track responses for additional control and introspection.
