* Update docs/submodules/compass4nfv from branch 'master'
  - Fix install netmask

    Netmask of install network is parsed from
    netwok.yml now. A var named INSTALL_NETWORK
    will be generated in script/deploy_config.sh
    and exported. But var of install mask in
    deploy/network.sh is called INSTALL_MASK.
    This mismatch cause empty netmask of install
    network.
