Instead of computing a coloring for one condition first and then refining
it for the other condition, we can construct a graph with edges for all
conditions that prevent simultaneous reboots. This will not only result
in simpler code, but might also lead to better colorings.

Renaming the current parameters dealing with spindles is nice, as their
meaning would be clearer, but that would mean changing a lot of code,
change external interfaces, and renaming internal variables for little
benefit. Also, instance policies would end up containing two related
parameters, one used when exclusive_storage is enabled, and the other when
disabled. Reusing the existing parameters by changing slightly their
semantics makes more sense.

This patch rewrites and extends the design doc about storage reporting
with respect to disk templates and storage types. In constrast to the
previous version, we now consider disk templates as the user-facing
entity, that the user can dis/enable for the cluster. Storage types
on the other hand describe the underlying technology used by the various
disk templates. Storage reporting will use a mapping from disk templates
to storage types to pick the correct method to report the storage for
the respective disk templates.

Note that the design doc in this state still contains some questions and
FIXMEs. Feel free to comment on those. I will complete them directly or
in future patches.

This patch adds the currently known and used storage methods to the
constants.py file. Note that storage types are different from disk
templates. For example both disk templates, drbd and plain, use lvm
storage types.

The rapi documentation asserts that valid storage types are limited
to lvm and file. With the extension of storage types, this is not true
anymore, but the implementation of listing storage units is not
implemented for the new types. We disable the assert for now, adding
a fixme to extend it once the listing of storage units is extended
for the new types as well.

'gnt-node list-storage' currently does not support any other storage
type than 'lvm' and 'file'. We limit the QA to storage types that are
currently implemented for this operation.
