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....

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,...

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....

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

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)...

Use -device with pci info if possible

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

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....

Prepare block_devices runtime entry

With this patch we add another entry in runtime files along with
kvm_cmd, kvm_nics, and hvparams. block_devices that used to be
encapsulated inside kvm_cmd, live now separately just like nics do
but in tupples of (L{objects.Disk}, dev_path)....

Prepare kvm options to support -device for disks

Newer kvm version support -device driver,... option where available
drivers can be found by running kvm -device ? command. Currently
ganeti uses `if` property of driver to define the disk type to use
which is also passed as hvparam. This patch prepares the use of...

block_devices = (disk, link, uri)

Do not pass BlockDev instance to hypervisor. Instead calculate the
drive_uri (if any) in backend level and pass only the string to
hypervisor.

Hypervisor should not be aware of the entire block device but only
the final path it can be reached....
