Change the total disk/mem to Double

Since we only use the totals for computations, and we always convert
them via fromIntegral, let's just store them directly as Doubles.

A no-code change s/disk/dsk/

This just makes indendation nicer in many expressions.

Compute the p_mem / p_dsk statically

This patch changes the computation of p_mem / p_dsk from on-demand
(whenever the cluster stats are computed) to after-modify (after a node
is modified, we update its stats). This brings a god speed-up as only
one node or two are usually changed between cluster-wide stats are...

Simplify the checkInstanceMove function

This patch flattens the two folds into one, by simply building the whole
list of moves instead of the double recursion (nodes and the each
node's moves). This has no functional change, but it's much cleaner.

A small optimization in node computation

Currently we always compute the available node list for moves (for an
instances) based on the nodes of the initial table. This works find,
however is a repeated calculation.

We optimize this by passing a node list (of indexes, not full objects),...

Split checkMove into two

This cleans up and splits the individual instance move into a separate function.

Change the balancing algorithm

This patch changes the balancing algorithm to not iterate linearly over
the instances (in a random, but fixed order), instead selecting at each
step the best next move. This should allow a better score (most of the
time), and usually also a shorter solution.

Add RAPI support to hn1

This patch moves a function to Utils and changes hn1 to be able to take
data from RAPI.

Do not try both http and https against the server

This patch changes the tryRapi function so that if the http request
succeeded, we don't try https too.

Simplify some JSON transforms

... hopefully this is more clear.

Add compatibility with rapi v1

The patch adds compatibility with RAPI v1, and this required some new
JSON functions as valFromObj doesn't behave nicely.

Some other unrelated changes were done too.

Fix a bug in Cluster.fixNodes

We need to lookup the moving accumulator, of course.

Make RAPI return the same data format as gnt-*

This patch changes the RAPI endpoint return the same data format as the
input files. This will allow using it instead of the files.

Change the input file formats

This patch changes the format of the input node and instance lists. It
removes the list of primary and secondary instances from the nodes, and
adds the primary and secondary nodes to the instance list.

This is done so that we can have the same input data from commands as...
