Spindles become part of htools resource spec

Spindles are now part of resource spec. Instances get created with spindles
specified (which are just ignored when exclusive storage is disabled).

htools cluster score takes spindles into account

When exclusive storage is enabled, spindles are used instead of disk space
to compute the cluster score.

Comments and variable names in computePDsk has been changed to match the
actual code.

The existing tests are run also on nodes with exclusive storage enabled. The
values for spindles and exclusive storage are set in a consistent way, for
both nodes and instances.

Load complete instance disk information through LUXI

Information about size and spindles of all the disks of an instance is loaded
by the LUXI backend, instead of faking one equivalent big disk. In this way
instance policy checks are more accurate.

Load node spindles data in htools

The data structure for nodes gets a new field for free spindles, and the
existing field for total spindles gets renamed to avoid identifying it with
the node parameter that had the same name. These fields get filled with...

Add spindles to instance disks in htools

A new data type is introduced for disks to store both size and spindles.
When available, spindles are filled with input data. Except for loading and
storing, spindles are ignored.
