* Update docs/submodules/fuel from branch 'stable/fraser'
  - AArch64: Switch to upstream Saltstack repo

    To work around the missing dependency of 'python-tornado' on
    'python-features' provided by the binary-specific DEB package
    in amd64 Saltstack repository, pre-install the req explicitly
    on FN (jumpserver) and VCP VMs via lib.sh.
