Cloud-Init support for Raspberry Pi (ARM)

Reference for Raspberry Pi custom cloud-init config module: https://cloudinit.readthedocs.io/en/latest/reference/modules.html#raspberry-pi-configuration

Config files are installed to /boot/firmware/ so they are accessible from the
boot partition before the root filesystem is fully mounted.

- files/network-config  Network configuration template (netplan format)

- files/user-data       Example user-data configuration

- files/meta-data       Cloud-init instance config (instance_id: rpios-image)

The rpi-cloud-init-mods package (from 00-packages-arm-only) provides additional
Raspberry Pi specific cloud-init modules.
