(2.10) Introduce _UpgradeSerializedRuntime() method

This method is invoked during _AnalizeSerializedRuntime() and is
meant to modify runtime files in the way cfgupgrade does for
config.data. This could remove deprecated fields, change the
format of the file, add/remove sections, etc....

(2.10) Export NIC's UUID and name to network scripts

In case of kvm None values are not allowed in env dict
so we have to add name only if not None.

In case of Xen since we are writing on a file that
is going to be sourced we should not add INTERFACE_NAME=None....

(2.10) Introduce --hotplug-if-possible option

This will be useful for an external entity using RAPI that
wants to modify devices of instances.

The common use case for that is:
"I want to add a NIC/disk to an instance. If it is running
then try to hotplug the device. If not, then just add it to config."...

(2.10) Check if hotplug is supported in CheckPrereq

Introduce new RPC hotplug_supported that invokes the corresponding
hypervisor's method which checks if hotplug is generally
supported. Call this RPC early in CheckPrereq() and abort if
hotplug is not supported. Currently only KVM hypervisor with...

(2.10) drive_del after device_del in disk hot-remove

This is needed so that qemu process really releases the
corresponding file descriptor and thus we can dmsetup/lvremove
the device without errors.

(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) 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) 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....
