add with-local-disks option for live storage migration

Browse Source 
As Fabian as required,
add an extra flag "with-local-disks"  to enable live storage migration with localdisk.

default target storage is same sid than source, this can be overrided with
"targetstorage" option.

I will try improve this later, with optionnal mapping, disk by disk.
