Unit tests for spindles and exclusive storage in htools

Everything should work the same when exclusive storage is active, as
spindles are not yet handled as a resource. A new test has been added for
the interactions between spindles and policies.

Check real spindles in ipolicies

When exclusive storage is enabled, the spindles in instance disks are used
to check the instance policies (as outlined in design-partitioned.rst).

Check the full instance specs in htools

Spindles and disk count are checked too. Existing functions have been
refactored, so common parts are not duplicated.

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.

Export instance disk spindles

Instance disk spindles can be queried via LUXI and RAPI, and are exported
through the allocator interface. This is a prerequisite for htools to
handle spindles.

The length of a RAPI query including all the instance fields now has become...

Test with non-redundant instances and several node-groups

The example cluster contains two node groups. The first contains three nodes,
with two non-redundant instances each. As each node has only capacity for three
instances, the nodes have to be rebooted individually. Additionally, there is...

Restrict instance moves in hroller to the same node group

When scheduling rolling reboots, hroller looks for nodes to evacuate
the non-redundant instances to. This is done by greedily moving
instances to other nodes that can take them, policy wise and capacity...
