(2.10) hotplug: Each hotplug qemu commmand with a separate socat
Previously we issued one socat command with two "\n" separated
actions (e.g. netdev_add ...\ndevice_add...)
After having observed a strange monitor behavior [1] splitting
those commands and introducing a sleep time in between, may reduce
any race possibilities. Additionally it will be a step forward
parsing monitor output of each command and decide whether to
modify runtime files or raise a HotplugError.
This patch we simply changes _CallHotplugCommand() to take a
list of commands and issue them separately. Introduces one second
sleep after each command and removes sleep from HotModDevice().
