[PATCH 0/2] Change storage volume creation to async tasks

From: Royce Lv <lvroyce@linux.vnet.ibm.com> v1>v2, Change according to Aline's comments, Use list to track param index to avoid iteration. This is inspired by Cristian's patch.

Please, run "make check-local" to find formatting errors and fix them. Also, run "sudo make check" and fix the tests which are broken due to this patch.
-from kimchi.control.base import Collection, Resource +from kimchi.control.base import Collection, Resource, AsyncCollection
"AsyncCollection" should come before "Collection"
-from kimchi.utils import kimchi_log +from kimchi.utils import kimchi_log, add_task +from kimchi.model.tasks import TaskModel
"kimchi.model.tasks" should come before "kimchi.utils", and "add_task" should come before "kimchi_log".

This patch doesn't actually break anything. I was getting one test failure related to storage volume but the reason is that there was a "leaked" volume in the pool "default" created in a previous test execution, and when the current test tried to create a new one, an error showed up. I just had to remove that volume manually and everything worked fine. This has nothing to do with this patch (even though there's still a bug somewhere which leaks storage volumes). Sorry for the confusion.
