Fakelibvirt migrateToURI3 should provide args according to libvirt doc
Fakelibvirt migrateToURI3 should provide args according to libvirt doc

According to libvirt doc[1], migrateToURI3 supports
args(dconnuri, params, flags) but not logical_sum.
We call migrateToURI3 with arg flags in guest.py [2].

The wrong fake func may cause error in functional tests of nova.
With logs below:
  "/home/zuul/src/git.openstack.org/openstack/nova/nova/virt/libvirt/guest.py",
  line 669, in migrate'
  '    destination, params=params, flags=flags)'
  "TypeError: migrateToURI3() got an unexpected keyword argument 'flags'"
