Update git submodules

* Update docs/submodules/armband from branch 'stable/euphrates'
  - u/fuel: Bump & rebase for Ubuntu `modprobe -f` fix
    
    Squash in additional changes:
    - p/fuel: Retry armband state, fail on not connected
    - u/fuel: Bump & rebase for wait_for changes
    
    While at it, catch armband state minion timeout (not connected or no
    response) and reduce armband state retry from 10 to 5.
    
    We no longer expect the armband state to fail on any nodes,
    baremetal or virtual, kvm or cmp, so remove failsafe `|| true`
    and retry state apply in case minions did not repond.
