Add a docker role for making sure Docker is installed from the Docker
repositories.
Take the role from the ccchh-ansible repo, provide attribution in the
README and add the relevant license in a new licenses directory.
Modify the role by removing the distribution check and adjusting the
task names to be in line with other task names in this repo.
This playbook does the following:
- Creates a cit user (which has root privileges) using the cit_user
role.
- Sets the cit users ssh authorized_keys to the authorized_keys of the
root user.
