Limit the PVs used for disk growth with exclusive storage

The exclusive storage flag is passed along in the backend functions for
disk growth. LVM volumes handles the flag by reusing the same PVs, as disks
are constrained by the number of their spindles....

Refactor NodeInfo RPC regarding storage reporting

The NodeInfo RPC call is refactored to handle now more than
just storage reporting for volume groups.

Since NodeInfo now returns storage space information not
necessarily for volume groups, but also for other storage...

Integrate free space reporting for file storage

This patch integrates the free space reporting for file
storage. So far, it is only called, when the default
disk template is a file-based disk template ("file" or
"sharedfile").

Inline simple "alias" variables

Remove variables in the form "var = self.var" throughout all LU's. Those
"alias" variables make it harder to read the code (it's no longer
immediately clear what's a field and what's a local variable), and can
introduce subtle bug (especially when not used consistently and when...

Adapt striping to the requested number of spindles

Otherwise LVM may use a smaller number of PVs (spindles) to accommodate for
the default stripes.

Spindles are mandatory with exclusive storage

If they are not specified in the command line an error is reported. Also,
disk creation would fail without them.

QA has been updated.

New BlockDev methods to get spindles

Two new methods are created to get the number of spindles, one alone, and
one together with size. For devices that don't support spindles, None is
returned.

Attaching a logical volume builds a list of PVs

When an LV gets attached, the list of the PVs used by the LV is built. This
will be used to count spindles for exclusive_storage, but it could also be
useful to optimize disk growing and snapshotting.
