Additional disks when cloning a template

Contrarily to KVM creation, when cloning an existing template, even a c-i one, there is no way to add disks to the created VM. We can redimension them, but we must to stick to the partitions existing for the template.

Taking advantage of the new module community.general.proxmox_disk we will code the possibility of creating disks for your cloned VM on any of the storage present in your infrastucture.
