Remove custom OpResult type/monad

Since we now have the GeneralResult as a multi-purpose monad, we can
remove the custom OpResult monad, and just use 'GeneralResult
FailMode' as our type. This allows removal of a few bits of
specialised infrastructure, relying instead on the generic one....

Cleanup HTools.Types/BasicTypes imports

Before we reorganised the source tree, the 'Result' type was exported
from HTools/Types.hs. This changed during the reorg, but at that time
we didn't change the exports; instead, we kept re-exporting it from
the old module for compatibility....

Define the actual arguments that are supported by programs

This defines the arguments supported and then modifies the
--help-completion output to include them too.

Rename Ganeti/HTools/Utils.hs to Ganeti/Utils.hs

This is, I believe, the last non-htools specific file that still lived
in the htools directory; it's already widely used in non-htools code,
so let's move it before we add more functionality to this module....

Remove generic options from individual programs

Currently, we test and require that each individual program (hbal,
etc.) defines/supports the generic options (currently --help and
--version). Even with the test, this is not optimal, since it requires
changes in many places whenever we modify the list of generic options,...

Improve the prop_Alloc_sane test to detect mis-allocations

Currently, this just checks that a cluster cannot be rebalanced after
a single instance allocation. However, we can also test whether the
allocation decision computed a correct new cluster score, by checking...

Add new test for checking multi-allocations

This test expands the "single-alloc-no-rebalance" by allocating a few
instances on a small cluster, and ensuring that after we allocate all
of them, either we can't rebalance or if we rebalance the score
improvement is very small....

Improve the `CanTieredAlloc' test

Currently, this test is very slow. Upon investigation, this is due to
how `tieredAlloc' works:

- tries to allocate one instance
- if failed, shrink the instance by the "most failed" resource
- restart

In this algorithm, if the "most failed" resource is e.g. memory, and...

Improve the `AllocPolicy' test

This test has a few deficiencies, which this patch addresses:

- using arbitrary 1 or 2 node count for allocation is obsolete,
nowadays we need to use a number appropriate for the instance's disk
template (and we should remove that parameter…)...
