The timeout is always between ~0.1 and ~10.0 seconds. A small
variation of ±5% is added to prevent different jobs from
fighting each other. After 10 attempts to acquire the locks with
a timeout, a blocking acquire is made.

Lock status reporting will be improved in a separate patch.

This patch adds three optional parameters:
  - 'use_bootloader', whether use or not the bootloader
  - 'bootloader_path', absolute path to the bootloader
  - 'bootloader_args', extra arguments to the bootloader

Syntax:
  gnt-cluster modify --hypervisor-parameters \
    xen-pvm:bootloader_path=/usr/bin/pygrub,use_bootloader=False
  gnt-instance modify -H use_bootloader=True instance1.example.com

If use_bootloader is True, each domU can boot with its own kernel
instead of using the dom0 kernel.

ganeti-confd is a simple asynchronous daemon, which listens on a UDP
port, passes each packet to a processor, and sends back to the client
the result.

It also listens on an inotify socket, in order to reload its
configuration when the ganeti config file changes.

The method is changed to a normal loop, to avoid calling getattr()
twice. Also __getstate__ is changed to just use ToDict() by default.

This should also make __getstate__ work for objects which have to
override the ToDict function because they contain other objects.

__setstate__ is probably still broken in this case, but so it was
before, and it's not used inside our code, so I'll pretend not to have
noticed, as there is no "nice" way to fix it, without overriding it all
over the place :(

Some unittests are added as a bonus, to make sure we behave well.

Instead of multiple uploads to each node, this script copies everything
as needed to the temporary directory, exactly as to be installed in the
destination machine, then runs only one rsync per host.

This is more dangerous (we can break /etc now), but for development
machines is fine.

The patch then also uploads the bash completions and the current name
for the cron job (I think that ganeti-master-cron is a deprecated name,
not that someone actually intends to upload a file named like that). A
flag --no-cron is added to skip uploading the cron file if desired.

The patch also changes rsync to propagate the file permissions.

This patch adds a new hypervisor implementation: a chroot manager. This
hypervisor type can be used to manage (in combination with special OS
definitions) the start and stop of chroot areas, and if used with drbd
instances, it allows (via failover) the migration of chroots between
nodes.

This is a work in progress, and the way chroots should work is not very
clear and does not fit very well in the OS definition framework.
However, the hypervisor works and (if the sshd in the chroot is well
configured) it allows login to the instance both via ssh and console as
for a normal instance.

TODOs:
  - implement instance IP add/remove to/from the bridge, if the instance
    has a defined IP
  - investigate improvements to the OS API so that the create script has
    more information available, e.g. about the hypervisor type
  - mount extra disks in the chroot or alternatively refuse to start
    with more than one disk
