Add Ganeti.HTools.Graph

This module implements some algorithms on Data.Graph data structures.
At the moment its main functionality is an LF-color implementation
(greedy coloring in descending order of degree). There are also a few
extra functions to calculate the degree order, and convert the node to...

Switch luxi submit job calls to use MetaOpCode

This patch changes the luxi submit job calls to use wrapped opcodes,
and therefore it changes Hbal to submit actual meta opcodes. For
nicety, hbal also submits a comment now, showing who generated the
job.

hbal: restore nice job ID display

This fixes:

Got job IDs JobId {fromJobId = 1052613}

And restores to:

Got job IDs 1052624

Other improvements could be done here, of course.

Fix long lines in Ganeti.HTools.Types and add Make check

Since hlint doesn't check style issues but rather code only issues,
let's add a simple Makefile check for too-long lines, and fix the
single bad case we have currently.

Rework/enhance original htools opcodes

The original htools opcodes were minimalistic and not 1:1 equivalent
with the Python ones. Let's add all missing fields and, since we
changed the order, switch to more readable record syntax for building
the opcodes....

Fix variable names in Loader.assignIndices

This function can be applied to any type of class "Element" but its
internal variables used to refer to a list of tuples containing these
elements and their names as "nodes". Moreover it built a list of name to
indices tuples referring to it as "na" (which is not very clear)....

Change -G option description

The new one is more consistent with the rest of the nodegroup
terminology and more generic for use in different htools.

Remove read instances from our Haskell code

It turns out that optimising 'read' derived instances (via -O) for
complex data types (like OpCode, or the various objects) can be slow
to very slow. Disabling such instances results in (time make
$all_our_haskell_binaries) large compile-time savings and also smaller...

Replace hand-coded 'live' field of OpInstanceMigrate

This is the last inline-written field; I've done it separately from
the last patch due to changes being needed in HTools (field changed
type).

Convert a few existing opcode parameters to safer types

This does a partial conversion of existing opcodes to the new
non-empty string type, which is needed so that we don't add even more
opcodes without this safety net (and to have consistent "target_node",...
