notes:
  - Instances can be a container or a virtual machine, both of them must have unique name. If you attempt to create an instance
    with a name that already existed in the users namespace the module will
    simply return as "unchanged".
  - There are two ways to run commands inside a container or virtual machine, using the command
    module or using the ansible lxd connection plugin bundled in Ansible >=
    2.1, the later requires python to be installed in the instance which can
    be done with the command module.
  - You can copy a file from the host to the instance
    with the Ansible M(ansible.builtin.copy) and M(ansible.builtin.template) module and the `lxd` connection plugin.
    See the example below.
  - You can copy a file in the created instance to the localhost
    with `command=lxc file pull instance_name/dir/filename filename`.
    See the first example below.
