Export instance disk spindles

Instance disk spindles can be queried via LUXI and RAPI, and are exported
through the allocator interface. This is a prerequisite for htools to
handle spindles.

The length of a RAPI query including all the instance fields now has become...

Export connected networks to IAllocator

IAllocators should not put instances on nodes in nodegroups which are
not connected to the network the instance should be connected to.
Therefore, export the networks a node group is connected to to the
IAllocator, so it can account for this restriction....

Add disks_active to configuration

This flag tracks if the disks of an instace are supposed to be active.
That's the case when an instance is running or when its disks got
activated explicitly (and in a couple of other cases).
It will be used by watcher to re-activate disks after a node reboot....

RPC 'node_info': <storage_type,key> instead of vg_names

This replaces the field 'vg_names' in the RPC call of 'node info' by
'storage_units'. A storage unit is a tuple <storage_type,key>
and a generalization of a vg_name. The list of vg names is replaced by...

The disk size of a diskless instance is 0, not None

For diskless instances it is still reasonable to sum up the disk usage
of all the (zero) disks, resulting in the empty sum. This uniformity
also has the advantage that iallocators (like hail) do not have to do...

Allow iallocator to work without LVM storage

Currently, the iallocator interface requires LVM storage, due to the
way it computes the node storage information.

By changing the code to understand that GetVGName() can return None,
and by setting the disk_total/disk_free node parameters to the value...

Rename lib/objectutils to outils.py

Back when this was introduced, I mentioned that it breaks heavily tab
completion (ob<TAB> doesn't work anymore), but at that moment I didn't
have a suggestion what to name it. I think outils is good and short
enough, and doesn't conflict with anything else, so here it goes....

Add exclusive_storage parameter to node_info RPC

The flag is passed to the low-level functions that need it, but it's not
yet used. Also, RPCs get just a default value for now.
