* Update docs/submodules/fuel from branch 'master'
  - [baremetal] cmp: run linux.network before reboot

    The recent addition of `linux.system`, combined with `system.reboot`
    for the baremetal compute nodes leaves compute nodes unconfigured
    after reboot.
    Run `system.network` too, but expect a failure (only for DPDK, which
    requires hugepages to be already active, hence a prior reboot).

    Fixes: 64920b8
