Change the module import hierarchy

This patch makes the Types module a base module, and Node/Instance ones
import it, from the previous (opposite) situation. This will allow in
the future to use newtypes for the index and name types.

Remove the ktn/kti from second half of loading

This removes the return of ktn/kti from Loader.mergeData and associated
functions.

Remove most uses of ktn/kti

This patch removes all uses of ktn/kti from the past-loader stages.

Remove some extraneous uses of ktn/kti

Since we have Node/Instance.name, we can now simplify a few constructs.

Move common loading sequence in CLI

This patch moves the common loading sequence to CLI, such that hbal/hn1
and possible future scripts that take the input from same sources can
use it.

Move checkData from Cluster to Loader

This moves the remaining loading function to Loader (together with its
associated support functions).

Introduce a class for CLI options

This patch generalizes a little the CLI handling by not passing in a
special function for help and such, but instead requiring that the
options object supports some common functionality.

More code reorganizations

This new big patch does a couple of more cleanups in the loading of data
chapter:
- introduce a Types module that holds most types (except the base
Node/Instance/etc.) so that multiple other modules can use these
(instead of only Cluster and its users)...

Rework the loader model

This big patch changes the loader model from “string data as common
format” to actual object structures as common format.

The text loading function move from Cluster.hs to a new Text.hs module,
some common functions are moved to a new Loader.hs module, and the...

Convert Cluster.loadData to Result return

This patch changes Cluster.loadData to return a Result, instead of
directly the values; this will allow us to return meaningful error
values (e.g. when an instances lives on unknown node) rather than simply
abort. Currently the result is always an Ok, the actual signalling of...

Switch from hand-written monads to a real one

This big patch converts from our home-grown monad-like constructs
(the Either stuff) to a real, Either-like-but-another-name monad.

We introduce a “Result a” monad, and this allows dropping many of the
extra constructs. Hopefully the code is also more clear....

Add reading the file names from env vars

This patch adds support for selecting the instance/node file names via
two environment variables (HTOOLS_NODES, HTOOLS_INSTANCES).

Unfortunately we still have lots of duplicated code, since the options
are not unified.

Implement error checks for extra arguments

Neither hbal nor hn1 take any arguments beside the options, so if any
are passed is most likely an unintended error. This patch aborts in such
cases.

Show the x_mem/i_mem in node list

This patch adds checking of cluster data in the binaries and display of
node's x_mem/i_mem in the node list.

Split common CLI functionality into a module

This patch moves the common CLI functionality (as much as currently
possible) into a separate module. This means we only have one parseOpts
and that Utils.hs doesn't keep this kind of functions anymore.

Introduce a namespace for the modules

The modules are moved from the ‘top’ namespace to ‘Ganeti.HTools’, in
compliance with standard practices.
