Update git submodules

* Update docs/submodules/fuel from branch 'stable/euphrates'
  - Merge "lib.sh: Fix locals override in nested invocations" into stable/euphrates
  - lib.sh: Fix locals override in nested invocations
    
    'wait_for' bash function is nested in another 'wait_for' call in some
    places, which leads to inner calls interfering with outer calls by
    overriding the locally scoped variables, including the 'attempt'
    internal counter. In some cases, the outer 'wait_for' would exit
    after a single attempt.
    
    Fix that by running all contents of `wait_for` inside a subshell,
    which inherits outer calls variables, but does not override them
    when the inner call is finished.
