Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - Merge "Bring in baremetal support"
  - Bring in baremetal support

    - ci/deploy.sh: fail if default scenario file is missing;
    - start by copying reclass/classes/cluster/virtual-mcp-ocata-ovs as
      classes/cluster/baremetal-mcp-ocata-ovs;
    - add new state (maas) that will handle MaaS configuration;
    - Split PXE network in two for baremetal:
      * rename old "pxe" virtual network to "mcpcontrol", make it
        non-configurable and identical for baremetal/virtual deploys;
      * new "pxebr" bridge is dedicated for MaaS fabric network, which
        comes with its own DHCP, TFTP etc.;
    - Drop hardcoded PXE gateway & static IP for MaaS node, since
      "mcpcontrol" remains a NAT-ed virtual network, with its own DHCP;
    - Keep internet access available on first interfaces for cfg01/mas01;
    - Align MaaS IP addrs (all x.y.z.3), add public IP for easy debug
      via MaaS dashboard;
    - Add static IP in new network segment (192.168.11.3/24) on MaaS
      node's PXE interface;
    - Set MaaS PXE interface MTU 1500 (weird network errors with jumbo);
    - MaaS node: Add NAT iptables traffic forward from "mcpcontrol" to
      "pxebr" interfaces;
    - MaaS: Add harcoded lf-pod2 machine info (fixed identation in v6);
    - Switch our targeted scenario to HA;
      * scenario: s/os-nosdn-nofeature-noha/os-nosdn-nofeature-ha/
    - maas region: Use mcp.rsa.pub from ~ubuntu/.ssh/authorized_keys;
    - add route for 192.168.11.0/24 via mas01 on cfg01;
    - fix race condition on kvm nodes network setup:
      * add "noifupdown" support in salt formula for linux.network;
      * keep primary eth/br-mgmt unconfigured till reboot;

    TODO:
    - Read all this info from PDF (Pod Descriptor File) later;
    - investigate leftover references to eno2, eth3;
    - add public network interfaces config, IPs;
    - improve wait conditions for MaaS commision/deploy;
    - report upstream breakage in system.single;
