migration/qmp: add command migrate-pause
It pauses an ongoing migration. Currently it only supports postcopy. Note that this command will work on either side of the migration. Basically when we trigger this on one side, it'll interrupt the other side as well since the other side will get notified on the disconnect event. However, it's still possible that the other side is not notified, for example, when the network is totally broken, or due to some firewall configuration changes. In that case, we will also need to run the same command on the other side so both sides will go into the paused state.
