Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "ci/deploy.sh: Move global vars to separate file"
  - ci/deploy.sh: Move global vars to separate file

    log.sh should also work as standalone script, so factor out
    global variables from <ci/deploy.sh> into <mcp/scripts/globals.sh>,
    which should be sourced by log.sh when required variables are not set.
