PreprovisioningImage should not be created on poweroff

PreprovisioningImage not created on poweroff

There is a new state StatePoweringOffBeforeDelete
that should not create the PreprovisioningImage.

This new state comes from a previous one called
StateDeleting that was contemplated about
not creating the PreprovisioningImage.

Just added the new state to nor create the image
