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...

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...

Add a small 'passTest' helper

This is symmetric to failTest, and allows us to use it in cases where
we need to return a property.

While replacing 'property True' with it, I saw a case where we can
simplify the use and thus reworked that check.

Fixup test suite names

The names were not in a proper hierarchy, leading to inconsistencies
about what they were actually tested.

We change this by reproducing in the test names the relative hierarchy
within the Ganeti directory, leading to nicer test suite names (in...

Simplify property and test case names

Since we now have separate namespaces due to the multi-file split, we
don't need to keep the name of the module in the property names, as we
don't have so many potential conflicts anymore.

We remove the group prefix handling from TestHelper and simply do a...

Split most HTools test code into separate files

Except for Ganeti.HTools.JSON, which needs rename, we split all the
other test suites into separate files.

We have to add another common test helper, due to import dependencies
(sigh), but otherwise this split is pretty straightforward....
