Convert query path from string errors to GanetiException

This patch converts all the call paths from 'Result' (which contains
just string errors) to 'ErrorResult', which holds
GanetiException-encoded errors. We can now return proper
OpPrereq/OpExec errors to the clients of the luxi/query socket....

Fixup hypervisor queries in node query

We need to only query the default (first enabled) hypervisor, not all
hypervisors. For this, we need to add a manual check to ensure that we
don't have a corrupt config (there's no "NonEmptyList" type…).

Config support for NodeGroup query

For some results in nodegroup queries we need agregation similar to
one that is done for nodes.

Further hlint fixes

Commit 2cdaf22, “Re-enable standard hlint warnings”, got it almost
right. The only problem is that (confusingly) the default set of hints
is not in HLint.Default, but in HLint.HLint (it includes Default and
some built-ins).

After changing the lint file to correctly include the defaults, we had...

Move JSON.hs and Compat.hs out from under HTools/

These two files are not htools-specific, so let's move them out of the
HTools subdirectory/module hierarchy and directly under Ganeti.

Add more node-related data types and functions

This is a simple type declaration for NodeRole, a NdParamObject type
class, and a few related helper functions for nodes and node groups.

Expand Objects.hs definitions

This patch adds the missing parameters in the cluster/group objects,
for now as simple maps (dictionaries), without type safety. The
rationale for adding them as such is:

- we need something to enable query functionality
- since we don't modify the values, we don't risk introducing bugs...

Config.hs: Add a function to lookup group

Like in the python code, this is a bit more complex since groups are
indexed by UUID, so we must fallback to lookup via the name (slow; but
the number of groups should be small).

Re-enable standard hlint warnings

Commit 5a1e31b4 (Add infrastructure for, and two extra hlint rules)
was intended to add two extra hlint rules, but I didn't realise at
that time that "--hint" when first used overrides the built-in
lints. As such, since then we were basically running with just those...

This is the first part of the changes related to the 'Container' type.

We currently handle this type as follows: it's a simple type alias
