Bug#1007182: live-config: Add ability to use cloud-init for configuration

[Michael Kesper <mkesper@fsfe.org>]

Package: live-config
Version: 11.0.3
Severity: wishlist

Dear Maintainer,

Please add the ability to configure debian live media per default
with the cloud-init standard.
Cloud-Init can already be used for VMs starting with debian cloud images
and offers declarative configuration of many aspects, see
https://cloudinit.readthedocs.io/en/latest/
Live media should search on the modifiable file systems for such
configuration items, removing the need for rebuilding whole images
for simple adaptations.

Feel free to move to another package if this is the wrong address.
