Add ansible_managed to templates

[dirn]

When looking at configuration files on a host, it's often helpful to
know when the file was generated by a configuration management tool.
Ansible provides this through the ansible_managed context variable.

Indeed. For those who do not want changed notifications to happen and see their servers restarting every time the role is run even if there is no change (because of the date in ansible_managed), you can set your own value in the configuration file:

ansible_managed = Ansible managed, do not edit directly: {file} by {uid} on {host}
