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....

Add lookupGroup utility function

This will be used in the various backends similar to the lookupNode
function.

Improve error reporting for small clusters

When doing a two-node allocation on a cluster/group in which only one
node is online, or a one-node allocation without any online nodes, we
didn't show a valid error mesage. The patch changes tryAlloc to "fail
hard" in this case, to make the failure explicit....

hail/allocate: implement multi-group support

This is a bit hackish. We add a new function that takes the input data,
splits it into groups, runs the original tryAlloc for each group, and
then chooses the best solution, but adds the log messages from all the...

Add a 'log' attribute to allocation solutions

And also a couple of functions for describing a given solution; these
will be used in the future instead of the ones currently in hail.

The patch also enhances the description of failure messages.

Change AllocSolution from tuple to its own type

Tuples are good for two, three, at most four elements. Beyond that, the
continuous pattern matching and construction/deconstruction becomes
tedious.

Since in the future we'll probably keep more information in the...

Cleanup AllocSolution after AllocElement changes

Since we added the score to AllocElement, we don't need to wrap
AllocElement in yet another tuple, just to attach the cluster score. So
we simplify the AllocSolution type.
