With a large job queue, auto-archiving jobs can take a very long time,
causing timeouts on the luxi RPC layer. With this change, auto-
archive returns after half of the RPC timeout has passed. The user
will see how many jobs are left unchecked.

Currently we have to update both the ListNodes headers and the online
help for the full field list. This patch uses the headers keys for the
help, thus removing duplicating places to update, and adding hope that
we'll have things in sync. As a downside we lose ordering of the
non-default fields in the online help.

On cluster init if the user specifies a default hypervisor (with -t)
which is not in the default list of enabled hypervisors (currently just
xen-pvm) without explicitely specifying the list we silently override
the choice.

With this patch we set the list by default to just the required one, and
we bail out should the list be hand-specified and not contain the
default one. This still has an issue when the user doesn't specify a
default hypervisor but specifies a list which doesn't include xen-pvm:
in this case though we give an error, rather than silently discarding
choices.

Currently, the node add operation uses a job to query the node name and
the bootstrap function directly reads the config file for the cluster
name.

This patch changes to that both the cluster name and the verification of
the node is done via queries to the master.

This big patch adds support for:
  - changing NIC/disks in the multi-device model
  - adding/removing NICs
  - adding/removing disks

The patch is big and not very nice; the error checking paths are not
very clear.

The biggest problem is that from a simple instance.ATTR=VAL change
(which didn't throw errors before) now we are creating and removing
disks in this LU.

This patch enables by default the old 'human-readable' option, but in a
slightly different model.

The option is now called "units" and takes either:
 - 'h' for automatic formatting
 - 'm', 'g' or 't' for mebi/gibi/tebibytes

If 'h' is used, we add a unit suffix, otherwise nothing is added so that
parsing is easy.

The default value of this unit is:
  - 'h' if a separator is not passed
  - 'm' if a separator is passed
