ifdown: Extract env creation from ConfigureNic()

Introduce new helper method that creates the environment passed
to ifup/ifdown scripts. Instance tags and NIC index will be passed
only during ifup script since only then are available and
valid. Both can change until a NIC gets removed and thus will not...

ifdown: Introduce helper methods

Until now Ganeti upon TAP creation, a NIC file was created
under $RUNDIR/kvm-hypervisor/nic/<instance_name>/<nic_index>

Since NICs have obtained a UUID, we are going to create another
file named after its UUID. This will be needed during ifdown...

(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'....

(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...

(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....

(2.13) kvm: Add migration capabilities as an hvparam

Latest QEMU versions support various migration capabilities. Each
can be enabled/disabled with 'migrate_set_capability' monitor
command.

Version 1.7.0 defines x-rdma-pin-all, auto-converge, zero-blocks,...

KVM: use running HVPs to calc blockdev options

Commit 0fe22ad2 moved the call to _GenerateKVMBlockDevicesOptions() from
_GenerateKVMRuntime() to _ExecuteKvmRuntime. However, while in
_GenerateKVMRuntime() there is only one set of HVPs, those of the
instance's configuration, in _ExecuteKVMRuntime there are two sets of...

KVM: reserve a PCI slot for the SCSI controller

Currently instances with disk_type=scsi are broken, because the SCSI
controller uses a PCI slot not accounted for in the PCI assignment
logic. We reserve a throw-away slot just for that.

This is a temporary workaround and will be reverted during the upcoming...

Fix conflict between virtio + spice or soundhw

With regard to PCI slot occupied by a KVM instance we have
observed the following:

1) Slot 0 will always be Host bridge.
2) Slot 1 will always be ISA bridge.
3) Slot 2 will always be VGA controller (even with -display none)....
