add copy image to volume api

Registered by Bin Zhou on 2017-04-21

Nowadays cinder provide api to create a bootable volume by create from image, but there is no way to create a bootable volume from an existed blank volume. This blueprint is to add a copy image to volume api, which will copy a provided image to the existed volume. what's more, create an image volume will be spearated to 2 apis of 'create' and 'copy image to volume', which would be more atomic.
