Rename/make uniform the other query entities

Following the new naming style introduced in Exports.hs, this patch
renames the other resources to export non-qualified names (fieldMap as
opposed to nodeFieldMap), and to use qualified module imports.

Also fixes a haddock issue in a docstring....

HRoller: allow filtering by node group

Accept the -G option, and if it's passed require that it matches a
nodegroup, then only output nodes belonging to that group.

HRoller: print only online nodes

To make the graphs work even when instances live on offline nodes (eg.
because we're offlining them just to exclude them, or because they have
instance still on them) we just filter them out at the end, when we're
going to print out the result....

Improve the rpc-test program

This is an ugly patch, sorry. It adds the following features to
rpc-test, to help with (stress) testing the Haskell RPC client:

- customisable repeat count for the RPCs
- customisable parallelisation factor
- options to show timing stats and other information...

Implement Export queries in Haskell

This is a simple query as it has only two fields, however it's the
first query that doesn't have a clear 'base' object and 1:1
correspondence between such objects and the results (groups, nodes and
networks do so).

We keep nodes as the 'base' object, since that's what we want to...

Add export_list RPC call definitions

This is straightforward, as the call has no parameters and a very simple return type.

Improve TemplateHaskell code to support empty objects

Currently, an empty objects will generate warnings as the arguments of
various functions are unused. By adding conditional code for this, we
can support generation of empty objects, e.g. like needed in Rpc code....

Switch the RPC module over to the multi interface

This replaces the very-basic parMap of IO actions (fully serialised,
as parMap won't work here), to the multi interface.

This makes a simple "time gnt-node list" on a 6-node cluster go from
3.2s to ~0.9s, and allows even better parallelisation - before,...

Add a Ganeti-specific implementation of Curl Multi

As we want to be able to run queries against multiple nodes in
parallel, and furthermore in parallel with other work, we need to
implement the Curl Multi interface (see libcurl-multi(3)).

This patch adds a Ganeti-specific such implementation, to be used...

Add two utility functions for handling Either lists

These two functions permit operating in bulk on only the Left or Right
values in the original list, then reassembling the list back in the
original order.
