[OE-core] [RFC] Removing directdisk image creation

[Saul Wold]

Folks,

I am working on converting the live image creation into an IMAGE_FSTYPE 
and wanted to see if anyone was still using the directdisk images?

I propose removing the directdisk images.

I am cross-posting to get ensure a larger audience for this.

Thanks
