ifdown: Make Read/LoadKVMRuntime classmethods

.. and make LoadKVMRuntime() take instance_name rather than the
whole instance object as first argument. This will be needed during
instance cleanup where we the instance object is not available.

We are going to retrieve current NIC configuration from the runtime...

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 be passed...

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...

ifdown: Change kvm-if* scripts

  • Rename kvm-vif-bridge to kvm-ifup-custom
  • Search if /etc/ganeti/kvm-if*-custom is available
    and execute it instead
  • Pass positional argument to custom script

(2.13) Fix Xen's NIC file

Xen exports all environment variables to a file so that an
external script (see vif_script hvparam) can source it.
In case of multiple values per variable (e.g. TAGS), we
should use XXX="a b c" instead of XXX=a b c. Fix this.

(2.13) kvm: Delegate socket handling to monitor module

Introduce @_ensure_connection decorator that properly handles
the socket connection (i.e. connect, close) and propagates
any exceptions raised in the decorated method.

In general @_ensure_connection wraps external methods....

(2.13) kvm: Use vhostfds obtained by OpenTap

During instance startup, if vhost_net is True, OpenTap() opens
/dev/vhost-net device to obtain some fds. These fds were never
used. This patch adds the vhostsfd option to the --netdev option.

(2.13) hotplug: Retry VerifyHotplugCommand up to 5 times

It seems that QMP upon device_del returns without QEMU having
completely removed the device from the PCI bus. This probably has to
do PCI bus hotplug handlers (DeviceState->BusState->hotplug_handler)....

(2.13) qmp: Log qmp commands and responses

Add debug logging for all qmp commands and responses, except for
query-commands, and qmp_capabilities, that are executed upon
initialization of QmpConnection (and their output is not really
useful).

(2.13) hotplug: Is not supported for QEMU < 1.7

Change the bulk check of whether hotplug is supported or not.
Only versions >= 1.7 support the required qmp commands.
