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...

Cleanup HTools.Types/BasicTypes imports

Before we reorganised the source tree, the 'Result' type was exported
from HTools/Types.hs. This changed during the reorg, but at that time
we didn't change the exports; instead, we kept re-exporting it from
the old module for compatibility....

Rename Ganeti/HTools/Utils.hs to Ganeti/Utils.hs

This is, I believe, the last non-htools specific file that still lived
in the htools directory; it's already widely used in non-htools code,
so let's move it before we add more functionality to this module....

Further hlint fixes

Commit 2cdaf22, “Re-enable standard hlint warnings”, got it almost
right. The only problem is that (confusingly) the default set of hints
is not in HLint.Default, but in HLint.HLint (it includes Default and
some built-ins).

After changing the lint file to correctly include the defaults, we had...

Add a helper function for mirrorType computations

We most always use `templateMirrorType . diskTemplate`, so let's add a

Since we use the functions always module-qualified, let's drop the

Fix a couple of bugs in handling offline instances

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

These will be used in Node.hs for proper add/remove instance
