Update git submodules

* Update docs/submodules/compass4nfv from branch 'master'
  - Bug fix for CentOS BM deployment

    JIRA: -

    In order to configure network for OSA deployment,
    it's needed to install some packages, such as
    bridge-utils, iputils, etc. So we configure
    external network before using yum to install
    packages.
