Final Message
-------------
**Summary:** output final message when cloud-init has finished
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
**Internal name:** ``cc_final_message``
**Module frequency:** per always
**Supported distros:** all
**Config keys**::
final_message: <message>
