internal/blueprint: add ignition customizations

Browse source 
This allows a user to configure the system via `edge-simplified-installer`
using an ignition configuration specified in the blueprint.

This ignition config can be embedded in the ISO as a Base64
encoded file (ignition.embedded.data) or as a file
containing the URL where the ignition config file is served
(ignition.embedded.url).

The user can also instead specify an URL serving an ignition
config file that will passed as a karg and be fetched at first
boot (ignition.firstboot.url).
