Fix setting of 'failN1' flag for corner case

This patch includes:

  • The 'failN1' flag is now only set if there is strictly less
    memory available than required for failover.
  • Unit tests for that.

Remove custom OpResult type/monad

Since we now have the GeneralResult as a multi-purpose monad, we can
remove the custom OpResult monad, and just use 'GeneralResult
FailMode' as our type. This allows removal of a few bits of
specialised infrastructure, relying instead on the generic one....

Instance.hs: rename 'tags' to 'exclTags', provide 'allTags'

The mergeData function in Loader.hs included a step to filter an instance's
tags to include only the exclusion tags (as specified via the commandline,
or cluster-level tags). Later on, code in Node.hs assumed Instance.tags to...

Handle nodes without local storage

Our current cluster model is based on per-node storage, and as such we
don't handle shared disk templates. Until we can improve the model,
let's handle nodes without local storage better: in order to still
compute 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 when
we 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.

This adds the spindleCount, hiSpindles and instSpindles attributes.

Remove Node.mCpu, replaced with the ipol vcpu_ratio

Since the iPolicy contains the vcpu_ratio now, we can remove the

Furthermore, we need to re-set the hiCpu value when changing the

Fix a couple of bugs in handling offline instances

The addition of the offline state for instances has introduced a few

Set group policy on nodes

In order to be able to use the group policy during allocation, we have

- add the policy as an attribute to nodes, or

Cleanup hlint errors

First, we update the recommended hlint version to what I used to get a
clean 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)...
