Update git submodules

* Update docs/submodules/compass4nfv from branch 'master'
  - Add workaround for horizon image upload issue

    JIRA: COMPASS-573

    1. With HORIZON_IMAGES_UPLOAD_MODE set to direct
    Horizon provides the endpoint for Glance based on
    OPENSTACK_ENDPOINT_TYPE. If OPENSTACK_ENDPOINT_TYPE
    is set to internalURL any browser outside the internal
    network is unable to upload image. Add ansible task to
    set HORIZON_IMAGES_UPLOAD_MODE to legacy as a workaround.

    2. Add ansible lookup plugin to get openstack release

    3. set openstack_release into group_vars/all in config-osa
    to make this variable readable for other tasks
