* Update docs/submodules/compass4nfv from branch 'master'
  - Merge "Seperate compass-tasks"
  - Seperate compass-tasks

    JIRA: -

    1. Keep openstack-ansible in compass-tasks-osa.
    Keep kubespray in compass-tasks-k8s. Build
    different compass-tasks in one tar ball. Identify
    which one to use during docker-compose.

    2. Temporarily using private docker repo.

    3. COMPOSE_IMAGES is used to controll which components
    to form compass-core regardless of specific repo. Set
    default value for openstack and kubernetes when perform
    single cluster deploy.
