This module configures the final message that cloud-init writes. The message is
specified as a jinja template with the following variables set:

    - ``version``: cloud-init version
    - ``timestamp``: time at cloud-init finish
    - ``datasource``: cloud-init data source
    - ``uptime``: system uptime

This message is written to the cloud-init log (usually /var/log/cloud-init.log)
as well as stderr (which usually redirects to /var/log/cloud-init-output.log).

Upon exit, this module writes the system uptime, timestamp, and cloud-init
version to ``/var/lib/cloud/instance/boot-finished`` independent of any
user data specified for this module.
