    """
    Creates a Compute Engine VM instance from an instance template, changing the machine type and
    adding a new disk created from a source image.

    Args:
        project_id: ID or number of the project you want to use.
        zone: Name of the zone you want to check, for example: us-west3-b
        instance_name: Name of the new instance.
        instance_template_name: Name of the instance template used for creating the new instance.
        machine_type: Machine type you want to set in following format:
            "zones/{zone}/machineTypes/{type_name}". For example:
            - "zones/europe-west3-c/machineTypes/f1-micro"
            - You can find the list of available machine types using:
              https://cloud.google.com/sdk/gcloud/reference/compute/machine-types/list
        new_disk_source_image: Path the the disk image you want to use for your new
            disk. This can be one of the public images
            (like "projects/debian-cloud/global/images/family/debian-12")
            or a private image you have access to.
            For a list of available public images, see the documentation:
            http://cloud.google.com/compute/docs/images

    Returns:
        Instance object.
