Move the RqType and Request types to Loader.hs

These two will be more generic than now, and belong somewhere else -
Loader.hs is a generic module for data loading, thus we move them there.

Add type synonyms for the node/instance indices

This is a first step towards full datatype renaming. That requires more
changes, so at first we only want to document clearly what is a node
index, what is an instance index, and what is a plain Int.

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.

hail: don't relocate to current primary node

This patch fixes the relocate-to-primary-node problem, and doesn't mark
the excluded nodes as offline anymore (we don't use them anyway, so
let's not use a different/fake cluster state).

hail: do not allocate on offline/drained nodes

This patch implements filtering out of the offline/drained nodes and
fixes a bug in IAllocator.hs parsing (similar to an older bug in Rapi.hs
from where the code was copied).

hail: cleanup unused options

hail: Implement non-mirrored instance allocation

This patch implements non-mirrored instance allocation, by allocating as
secondary node “noSecondary”.

hail: unify the post-processing of results

Both allocate and relocate compute new node lists, whose score must be
ranked and the best option chosen. This means we can convert the code to
a generic function.

Implement hail allocate (for 2-node requests)

This patch implements allocate for two node requests. One node requests
can be done as soon as we have a valid allocateOn function for single
nodes.

Working implementation if relocate

This patch completes the implementation of hail relocate. It maps all
valid destination nodes through a ReplaceSecondary IMove, filters out
the failed relocations, computes the resulting scores and picks the
lowest one.

Start implementing the hail functionality

This patch implements a very stupid (and broken) version of hail
‘allocate’.

Remove a function in hail

This is not yet used.

Remove some extraneous uses of ktn/kti

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

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)...

Initial work on hail

This makes hail compile and get a request parsed via IAlloc, but nothing
more.
