bump fuel-devops requirement to commit 'cce44f4'

Changes in fuel-devops:

- Add 'has_videocard' libvirt node attribute :
  allows to disable videocard, so the first network interface
  will have the name ens2 (default with videocard: ens3)

- Avoid race condition using parallel fuel-devops env manipulations
