image: Convert vmdk/vdi/qcow2 to strict CONVERSION_CMD types
The vmdk/vdi/qcow2 IMAGE_FSTYPEs predate wic. As such, they provide some similar underlying functionality in order to produce a "disk" image that in turn can be converted into different formats that various hypervisor types work with. They do not however provide the ability for other disk image types to be converted into these same output types. Furthermore, they are less flexible than what wic does provide. This drops the old style vmdk/vdi/qcow2 types and re-introduces them under the CONVERSION_CMD framework. The equivalent of vmdk is now wic.vmdk and so forth for the other types.
