This is either fuelclient bug or Nailgun.

Fuel API returns None for many calls, but fuelclient always expects JSON.

    Return a list of nodes on reprovision=false

    Unfortunetely, a type of response depends on inputs and that's what we
    have right now. By spending more time we can split this handle on two
    handlers to have more clear API for clients. But right now this patch
    fixes the problem with the response in NodeReassignHandler.
