Don't consider offline nodes as N+1 failed

This is just a cosmetic (I hope) change; the nodes shouldn't be used
anyway, and we only correct the display message.

Drop RAPI v1 compatiblity

Since we only support Ganeti 2.0, we drop the 1.2 compatibility.

Add support for 'offline' nodes

This patch drops compatiblity with Ganeti 1.2 and adds support for
offline nodes in the cluster. When reading from RAPI, the drained nodes
are considered offline so that we don't allocate on them too.

Update the IAlloc module

We know have a working parseData function that returns the node and
instance data. This uncovered bad support for non-drbd instances ☹

Move the JSON utilities to Utils.hs

This patch moves the generic/reusable JSON functions to Utils.hs, so
that they're shared between RAPI/IAlloc.

Add a copy of Rapi.HS as IAlloc.hs

This will be used in two ways:
- format the response to Ganeti (easy, implemented)
- parse the input data and build the node/instance lists (hard :)

hbal: Add a new min-score option

This new parameter causes the algorithm to finish (or even not start at
all) if we reach/have a score better than it.

hbal: Change hardcoded tests to monadic composition

In some case we manually do “if isNothing … then Nothing else …”, which
can be very easily replaced with a monadic construct in the Maybe monad.

Increase allowed missing memory to 512MB

Since Xen seems to “steal” some amounts of memory (depending on total
node memory), we increase the maximum allowed missing memory to 512MB,
based on gathered data from multiple machines.

Add reading the file names from env vars

This patch adds support for selecting the instance/node file names via
two environment variables (HTOOLS_NODES, HTOOLS_INSTANCES).

Unfortunately we still have lots of duplicated code, since the options
are not unified.
