Fix score calculation to work with empty clusters

Currently the cluster score calculation includes an offline instance
percentage, expressed as “offline inst / (offline + online inst)”, which
results in NaN for empty clusters. This patch changes the calculation...

Optimize the Utils.stdDev function

This patch optimizes the stdDev function in two respects:
- first, we don't do sum . map which builds an intermediate list, but
instead use a fold over the list to build incrementally the sum;
this should reduce both the time and space characteristics, as we...

Take the foldl out of Loader.fixNodes

Currently Loader.fixNodes is foldl' with a complicated function. It
makes more sense to take foldl' out of this function (and put it into
the caller) and let fixNodes be only this internal function.

Simplify Cluster.computeMoves

This patch changes the function Cluster.computeMoves to use guards and a
couple of subexpressions in order to greatly simplify it.

Fix hlint-generated warnings

This big patch cleans up the code per hlint indications. Many removals
of extra parentheses, replacements of concat . map with concabtMap,
extra dollar signs, eta reductions, etc. were performed.

The code still compiles and passes a couple of manual tests on sample...

Add computation of the failure reason in hspace

This patch enhances hspace to report why the allocation sequence
stopped, both in absolute error count and for the top reason.

Return correct failure data from Node.add*

This patch alters the Node.addPri/addSec to return correct failure data.
It removes the computeFailN1 function from the module as that used to
combine both mem and disk checks in the same function and thus the real...

Introduce a new type for allocation results

Currently the allocation/move operations workflow return ‘Maybe a’,
which is very convenient but loses all details about the failure mode.

This patch introduces a new data type which encodes the specific failure...

Remove hn1 and related code

hn1 was deprecated for a while and this patch removes it altogether. The
support code in Cluster.hs is also removed.

Fix totalResources avail disk computation

This uses the newly-added Node.availDisk to compute the actual available
disk correctl, and display the total allocatable disk in hspace.
