Support b_ssd storage with the template images provided by Scaleway

Support block storage in the packer builder with the images provided by scaleway

Description

In the documentation of the Scaleway Builder there is a param image_size_in_gb that says we can create an image with block storage but it doesn't work when I try to use it with the image provided by scaleway (here I used: Centos 7.6).

The error given by packer is the following :

==> scaleway: Error creating server: scaleway-sdk-go: http error 400 Bad Request: cannot create a volume of type b_ssd from a base of type l_ssd
Build 'scaleway' errored after 2 seconds 754 milliseconds: Error creating server: scaleway-sdk-go: http error 400 Bad Request: cannot create a volume of type b_ssd from a base of type l_ssd

My packer.json file looks like that :

"builders": [
    {

      "image_name": "name-packer-base-block-{{ user `ZONE` }}",
      "snapshot_name": "name-packer-base-block-snapshot-{{ user `ZONE` }}",
      "image_size_in_gb": "20",
      "type": "scaleway",
      "image": "centos_7.6",
      "zone": "fr-par-1",
      "commercial_type": "DEV1-S",
      "remove_volume": true,
      "ssh_username": "root"
    }
  ],

The feature seems not supported for the moment. Could you please implement custom image creation with block storage in the packer builder?

Use case

Creation of custom images with block storage without using the scaleway interface.

Sorry for my English. If you have any questions let me know. I appreciate your help.
