system task does not check if docker group exists

[mofrisch]

the following should be added before task "Create docker directory"

• name: Ensure group "docker" exists
  group:
  name: docker
  state: present

I'm also facing the problem with the docker directory. I think creating the directory before installing docker with the role from 'geerlingguy.docker' is wrong.
The initial-setup.yml is stoping after the error with the missing group and docker is never installed on my test system.
Fixing this in a proper way would be nice.

A added a task to create the group docker right before the task which creates the directory:

# roles/system/tasks/main.yml
- name: Create docker group
  group:
    name: docker
    state: present
  become: true
  become_method: sudo
  tags: [ always ]
