(2.10) Make hotplug related method raise HotplugError

Hotplug is not supported by default and thus we raise
HotplugError() for hotplug related methods.
If a hypervisor wants to support it, we must override VerifyHotplugSupport()
and implement the Hot* method....

(2.10) block_devices -> kvm_disks renaming

and a couple more styple fixes.
block_devices are misleading so rename them to kvm_disk (just like kvm_nics)

(2.10) Some fixes in _GenerateKVMBlockDevicesOptions()

  • Add docstring.
  • fix missed usecase of boot_disk=False if kernel_path is given.
  • Use devlist arg in GenerateKVMBlockDeviceOptions()
    This is previously calculated in _ExecuteKVMRuntime()
    so there is no need to rerun the same command....

(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) 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.
