Update git submodules

* Update docs/submodules/compass4nfv from branch 'master'
  - Merge "Copy ml2_conf.ini to ODL hosts"
  - Copy ml2_conf.ini to ODL hosts

    JIRA: -

    SFC test cases in functest need to read ml2_conf.ini to get
    ODL controller's IP and port. However they can only gei this file
    from control nodes. So we copy this from neutron server containers
    to ODL hosts.
