Hotplug: cmdlib support
Hotpluging is done by functions invoked by ApplyContainerMods(). In
order hotpluging to take place a --hotplug option must be passed.
If no --hotplug is passed during gnt-instance modify the modifycations
will take place after reboot.
A device is hotplug-able if it has a uuid after which it gets named from
the hypervisor perspective.
Before hotpluging a Disk it must be assembled. During
LuInstanceSetParams() newly created disks are not added to the instance
so _ExpandCheckDisks() in _AssembleInstanceDisks() will fail. So we make
this check optional only for this case.
In order to remove a disk (with blockdev_remove) it must be shutdown. So
after unpluging the disk _ShutdownDiskInstanceDisks() must be invoked.
Everything else is just like NIC hotplugging.
Add logging in case of hotplug.
