* Update docs/submodules/fuel from branch 'stable/euphrates'
  - [baremetal] Add upstream (lab) proxy support
    
    If upstream proxy is defined in IDF, propagate it to pillar data:
    - linux:system:proxy:keyserver:http(s) for cfg01, mas01;
    - maas:region:upstream_proxy for mas01;
    
    Sample IDF config:
    
    idf:
      fuel:
        network:
          upstream_proxy:
            address: 10.0.2.2
            port: 3128
