RHBZ 737921
Spice client is required to connect to the migration target before/as migration
starts. Since after migration starts, the target qemu is blocked and cannot
accept new spice client
we trigger the connection to the target upon client_migrate_info command.
client_migrate_info completion cb will be called after spice client has been
connected to the target (or a timeout). See following patches and spice patches.
