The AllInstancesInfo call appears to have been implemented but never

The KVM hypervisor Python class returned a "0" value for the times
field, which gets serialized as a string. As Haskell is more picky
about types, this caused the entire response to be declared as invalid
and broke status reporting. Fixed by changing the value to a proper
int.

Currently, when no explicit storage type is given, the
'gnt-node list-storage' command defaults to file storage
whether or not file storage is enabled on the cluster
or not. This patch fixes it by defaulting to the default
storage type (which is the storage type of the default
disk template). If this storage type does not support
space reporting, an error message is emitted.

This patch extends the man page of 'gnt-node info' to

Reviewed-by: Klaus Aehlig <aehlig@google.com>

This rather lenghy patch comprises a couple of refactorings
to achieve the following goals:
- 'gnt-node info' should only report space information about
  spindles, when exclusive storage is enabled on the node
  (so far it always did when lvm-based storage was enabled).
- 'gnt-node info' should report the disks' space information
  for the default disk template's storage. So far it did it
  always for LVM, which is irrelevant for a cluster running
  for example file-based instances.
- Performance tweaking of storage reporting and gnt-node
  info.
- Consider the future work on storage pools for any changes.

This is is achieved by the following refactorings:
- Move the decision whether or not to ask for spindle
  from cmdlib-level to rpc level.
- Move the decision for which disk template's storage
  information to ask for to cmdlib level (instead of
  requesting information for all storage units and
  later discarding most of them).
- Adjustments to storage utility functions.
- Affected unit tests are adjusted as well.
