Update git submodules

* Update docs/submodules/fuel from branch 'master'
  - [IDF] net_config: Add support for custom ip-range

    - submodule: bump Pharos to pick up installer adapter support, as well
      as IDF updates for Ericsson baremetal pod1;
    - labs/local/virtual: Bump mgmt, public networks start addresses from
      .1 to .10, similar to ericsson-pod1;

    While at it, drop patch now upstream and instead adopt the new param
    'neutron:server:root_helper_daemon'.
