Make NodeInfo (hs) accept arbitrary storage types

So far, the Haskell implementation of NodeInfo just
requests storage information about volume groups.
With this patch, storage info for abitrary storage
types can be requested.

Storage utility functions for Haskell

In order to extend the Haskell version of the NodeInfo
query, we need some utility functions to deal with
disk templates and storage types.

iallocator: computation of storage data

This patch extracts the processing of the storage-related
data from the RPC call 'node_info' in a separate function
to increase testability. In addition, this patch contains
unit tests for this function.

This patch changes the semantics of dealing with the result
of the RPC call "node_info" when converting them into a
LegacyNodeInfo. A legacy node info, can only hold storage
information about one storage type, which so far was always...

iallocator: factor out 'get_attr' method

This patch extracts an inline 'get_attr' method to extract
data from the result of the RPC call 'node_info'. It was so
far an inline function in the middle of a bigger method, which made
the code hard to read.

iallocator: prepare RPC call 'node_info'

This patch does a small refactoring in the allocator. It extracts
the preparation and actual call of the 'node_info' call into a
separate function. This is done for better testability. No functional
changes otherwise....

Unset LV name if no LVM disk templates are enabled

If there are no LVM based disk templates enabled in QA, reset the LV
name after the corresponding gnt-cluster modify tests. Otherwise
gnt-cluster verify would complain about the missing volume group.

Also make sure that no disk templates requiring LVM are ever enabled...

Skip drbd-usermode-helper test if DRBD is disabled

Changing the drbd usermode helper in gnt-cluster modify fails if DRBD is
not installed on the nodes. Thus skip this test if DRBD is not in the
set of enabled disk templates.
