Container: remove fromAssocList

Container.fromAssocList is just a re-export of IntMap.fromList; it
makes sense to remove it and simply export the original name, as it
needs just a bit of renaming in the rest of the code.

Convert the rest of the pipeline to ClusterData

This patch converts the backends and mergeData to the new ClusterData
type.

Simulation backend: read the allocation policy too

This patch moves the allocation policy from hardcoded to be read from
the given specification, and extends the error message for invalid
specifications.

Simulation backend: allow multiple node groups

This patch changes the behaviour of the --simulation option to be an
incremental option, where each new use defines a new node group. This
allows simulation of more complex clusters.

Change the Node.group attribute

Currently, the Node.group attribute is the UUID of the group, as until
recently Ganeti didn't export the node group properties. Since it does
so now, we make the following changes (again apologies for a big
patch):

- we change the group attribute to be an index, similar to the way an...

Rework the data loader pipelines to read groups

This (invasive) patch changes all the loader pipelines to read the node
groups data from the cluster, via the various backends. It is invasive
as it needs coordinated changes across all the loaders.

Note that the new group data is not used, just returned....

Rework the types used during data loading

This improves on the previous change. Currently, the node and instance
lists shipped around during data loading are (again) association lists.
For instances it's not a big issue, but the node list is rewritten
continuously while we assign instances to nodes, and that is very slow....

Add a type alias for UUIDs

This is to pottentially allow easier changes later.

Node: add the node group's UUID

This is not used anywhere yet, and the backend are all just adding the
default UUID, not the real one.

The patch also allows displaying the group UUID in the node list.

Simu loader: move the loading to non-IO code

While we don't actually have IO code in the Simu loader, we do have the
same interface. So we move the code again to a separate parseData
function which is exported.

Fix unused imports for ghc 6.12

GHC 6.12 has become more picky about unused imports, so we need to
remove/tighten some of them.

Introduce support for reading the cluster tags

While these are not actually populated from the backends, and all the
programs ignore them, this patch contains the changes in the function
types required.

Make some CLI options more consistent

Both the simulate and the tiered allocation mode take a machine spec on
input via a comma-separated list. This patch makes this a little bit
more consistent (always use disk,ram,cpu in this order).

Move some utility functions to Utils.hs

These were already duplicate (Text and Simu) and we need tryRead in more places.

Add a simulated cluster data loader

This is useful especially for hspace, where we might want to simulate a
hypothetical cluster to check allocation beforehand.
