Handle nodes without local storage
Our current cluster model is based on per-node storage, and as such wedon't handle shared disk templates. Until we can improve the model,let's handle nodes without local storage better: in order to stillcompute a valid cluster score, we need to handle nodes with tDsk == 0....
Track instance-used spindles in node set/add/remove
This simply tracks the instance-used spindles (using hard-coded '1'per instance), and additionally prevents additions in soft-mode whenwe go over the limit.
Note: there's an assymetry between addSec and removeSec (basically...
Shorten some function names
Since we use the functions always module-qualified, let's drop the`instance` prefix and use a shorter one.

Simplify logic in Node operations
This patch adds two helper functions and uses them for a somewhatsimplified logic in the add/remove pri/sec node functions.

htools: add support for listing spindles for nodes
htools: add spindle-related attribute to nodes
This adds the spindleCount, hiSpindles and instSpindles attributes.
The spindleCount is equivalent to spindle_count on the ganeti side (anode parameter). hiSpindles is the maximum instance-used spindles, and...
Remove Node.mCpu, replaced with the ipol vcpu_ratio
Since the iPolicy contains the vcpu_ratio now, we can remove theper-node mCpu value (which was the initial way to set this attribute).
Furthermore, we need to re-set the hiCpu value when changing thepolicy....
Fix a couple of bugs in handling offline instances
The addition of the offline state for instances has introduced a fewbugs related to their handling. The current code adds a helperfunction for making the check whether an instances uses reservedmemory on the secondary (and uses it instead of just autoBalance),...
Set group policy on nodes
In order to be able to use the group policy during allocation, we havea few choices:
- pass the group policy as a separate argument to all involved functions, or- add the policy as an attribute to nodes, or- add the group (not only the group index) as an attribute to nodes...
Cleanup hlint errors
First, we update the recommended hlint version to what I used to get aclean output (1.8.15). Most of the changes are:
- remove unneeded parentheses- some simplifications (intercalate " " → unwords, maybe … id → fromMaybe, etc.)- removal of some duplicate code (in previous patches)...

htools: rename Instance.auto_balance
… to autoBalance, per the recommended style.
htools: docstring fixes and improvements
No code changes (except one definition being moved around in QC.hs)are contained in this patch.
htools: some lint fixes
Removal of duplicate parantheses, removal of extra 'do', conversion fromnested if to guards, use hierarchical imports. All per hlint.
Node operations: take into account auto_balance
This patch changes the add to secondary/remove from secondary code tonot deduct/add the instance's memory if the instance is notauto_balanced.
