Alexandre Derumier b74cad8ae3 add live storage migration with vm migration
This allow to migrate disks on local storage  to a remote node storage.

When the target node start, a new volumes are created and exposed through qemu embedded nbd server.

qemu drive-mirror is launch on source vm for each disk with nbd server as target.

when drive-mirror reach 100% of 1 disk, we don't complete the block jobs and begin mirror of next disk.
(mirroring are parralel, but we try to mirroring them 1 by 1 to avoid storage && network overload)

Then we live migrate the vm to destination node. (drive-mirror still occur at the same time).

We the vm is livemigrate (source vm paused, target vm pause), we complete the block jobs mirror.

When is done we stop the source vm and resume the target vm

# time to complete and have side effects (not idempotent).
#
# The new implementation uses POST and forks a worker process. We added
# a new option 'background_delay'. If specified we wait up to
# 'background_delay' second for the worker task to complete. It returns null
# if the task is finished within that time, else we return the UPID.
