(ext) Pass disk geometry in kvm command

Currently we allow this feature only for ext templates that
allow arbitrary params per disk. If both 'heads' and 'secs'
params are given then 'cyls' is calculated from the disk size.

TODO: export these params in IDISK_PARAMS since the can be...

(ext) Override disk_cache hvp with disk param in ext

This is a hack that brings disk_cache hypervisor param
at disk level. This is supported only for disks of ext
template that allow arbitrary params. The corresponding
param that should be used is 'cache'....

(grnet) Enable -device option for old disks upon migration

Change _GenerateDeviceKVMId() to take device index as an
extra argument. In case device has uuid and pci info
we return proper device id. In case idx is given we return
a dummy id (e.g. hotdisk-0). Otherwise we raise an Exception....

(grnet) Move disk options before nic ones in kvm command

Older versions of Ganeti did ensure that during startup
disk devices will be inserted before nic devices in PCI
configuration space. KVM inserts devices to PCI slots
depending on the order of command line options....

(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) Export tags via GetTags() to network scripts

to NIC configuration scripts and files of kvm and xen hypervisors.

(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...
