Update git submodules

Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "log.sh: Collect /var/log from cluster nodes"
  - log.sh: Collect /var/log from cluster nodes

    Bring back <ci/deploy.sh> parameter `-L`, which is already passed by
    releng deploy script.

    Since we need to enable file_recv on salt master, do so by adding a
    new class in <virtual-mcp-ocata-common/infra/config.yml>, which will
    be inherited by all scenario reclass models.
