[Bug 1520538] [NEW] hyperv migration should report real PercentComplete

 

Public bug reported:

in Hyper driver, instance.progress is assigned by  migrate_disk_and_power_off
the instance.progress is calculated by  migrate steps,
this is not accurate.

there is "uint16   PercentComplete"  Msvm_ConcreteJob class
https://msdn.microsoft.com/en-us/library/cc136824(v=vs.85).aspx
which can get the actually PercentComplete of the migration.

we should use it as instance.progress.
