- Removed required_if.
  - Fixed doc strings.
  - Removed debug output being appended to actions.
  - Put import of basics at bottom to be consistent with other docker modules
  - Added 'containers' alias to 'connected' param
  - Put facts in ansible_facts.ansible_docker_network

lib/ansible/modules/cloud/docker/docker_network.py
