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....

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.

Fix iallocator for nodegroups with no tags

_ComputeNodeGroupData() raises error if a group has no tags
when list(gdata.tags) is invoked. Use “gdata.GetTags()” instead.

iallocator: Add node whitelist

In the future instance creations might have a lock on all nodes as was
the case until the implementation of opportunistic locking. Nodes for
which the lock is not held will be shown to the iallocator plugin as if
they were marked offline....

Cleanup ht's use of positive/strictpositive

Currently, ht.py uses a bad terminology for positive/non-negative
numbers. Per http://en.wikipedia.org/wiki/Positive_number, this is the
correct terminology:

- A number is positive if it is greater than zero.
- A number is negative if it is less than zero....

Rework the required_nodes field

This was used to verify the result of instance allocation. However, this
is not logic which belongs to the cmdlib rather than to the iallocator
request itself. So abstract it by its own function. And update the

Refactor IAllocator code

The IAllocator class was handling all the requests on its own, passing
in parameters on top level which works, but is hard to maintain and not
flexible.

With the upcoming change to the IAllocator for MultiAllocate we can't
use the toplevel parameters anymore. Therefore, we refactor the code...
