Update git submodules

* Update docs/submodules/fuel from branch 'stable/euphrates'
  - Merge "ci/deploy.sh: Add new `-E` arg for env erase" into stable/euphrates
  - ci/deploy.sh: Add new `-E` arg for env erase

    NOTE: In order to undefine VCP VMs with NVRAM (e.g. AArch64 VMs
    using AAVMF), an additional parameter should be passed to libvirt
    by Salt virt core module (equivalent to `virsh undefine --nvram`).

    While at it, pass CI_DEBUG, ERASE_ENV enviroment variables to
    state execution, and stop force-applying patches.

    Also refactor the rsync between foundation node and Salt master,
    so the whole git repo is copied as </root/opnfv>, and <root/fuel>
    becomes a link to it; useful for Armband, where 'fuel' is a git
    submodule. Fix .git paths after rsync, so git submodules work as
    expected in cfg01 repos.
