Title: Support for '"iso_checksum_type": "none" in builders with ISOs

When creating a vm with virtualbox or vmware, if you specify "iso_checksum_type" as "none", the builder will not require a iso checksum value and allow you to download the ISO. When downloading without a checksum, packer outputs a warning before the download starts.
