We should start using `{{ ansible_managed }}` at the top of our template files.


> Six additional variables can be used in templates: ansible_managed (configurable via the defaults section of ansible.cfg) contains a string which can be used to describe the template name, host, modification time of the template file and the owner uid, template_host contains the node name of the template’s machine, template_uid the owner, template_path the relative path of the template, template_fullpath is the absolute path of the template, and template_run_date is the date that the template was rendered.
