[Kimchi-devel] [PATCHv1 2/5] Storage volume upload: Change storagevolumes to AsyncCollection

[lvroyce0210 at gmail.com]

From: Royce Lv <lvroyce at linux.vnet.ibm.com>

Because storage volume create will include upload and download,
storagevolumes will not present before async task's finished.
so change storage volumes to async collection.
