(2.10) Hotplug: cmdlib support

Hotplugging is done by functions invoked by ApplyContainerMods(). In
order hotplugging to take place the --hotplug option must be passed
otherwise the modifications will take place after reboot.

NIC hotplug supports add, remove and modify. The modify is done by removing...

(fix) SetDiskID() before blockdev_assemble()

Before blockdev_assemble we call SetDiskID() in order to fill up
physical_id of disk needed by bdev.Assemble and eventually by
constructor of each BlockDev.

This is not needed in 2.10 since physical_id has become deprecated....

(2.10) Return link_name in blockdev_assemble rpc

Until now this RPC returned only dev_path. Since we use it in
hotplug we have to know the simlink of the device so that we
pass it to the corresponding hypervisor command and include it
in block_devices entry in runtime files....

(2.10) Introduce hotplug methods (hypervisor inteface)

4 new methods: HotAddDevice, HotDelDevice, HotModDevice, HotplugSupported
All these are the hypervisor interface with the backend.
In general they read current runtime info, do the actual hotplug
and update the runtime file....

(2.10) Hotplug: rpc support

Introduce new RPC that eventually invoke hypervisor specific
hotplug functions. In order to be generic it has the following
arguments: device type, action, device, extra info, seq.
Device type can be NIC or DISK, action can be ADD, REMOVE,...

(2.10) Extract socket related code from QmpMonitor class

Separate unix socket related code from QmpMonitor class and
make the latter extend the newly introduced one: MonitorSocket

(2.10) Use -device with pci info if possible

Extend kvm_cmd with -device option for the case of paravirual
Disks and NICs.

(2.10) Helper methods that check for hotplug support

Hotplug is currently not supported for:

- KVM < 1.0
 - existing devices in the cluster
 - python-fdsend module is not installed (NIC hotplug)
 - chroot (Disk hotplug)
 - security mode other than None (Disk hotplug)...

(2.10) Helper methods for PCI slots and device ids

Device naming:
QEMU monitor expects devices to be uniquely named. Device ids derive
from the following function:
kvm_devid = <device_type>-<part of uuid>-pci-<pci_slot>
Device ids must be reproduce-able when we want to remove them....

(fix) Remove uri slot from block_devices

In stable-2.10 we have userspace access mode for rbd. Backend
calculates uri along with link and dev_path. Thus we have
three items in block_devices and kvm_disks tuples.

We this patch we remove the third value.
