htools: read/save the disk template in Text backend
This requires that we change the signature of loadInst in order toproperly annotate the error messages, which in turn requires moreunittest changes.
Also, this invalidates yet again saved data files…...
htools: add DiskTemplate to instance definition
Currently always fixed to DRBD8, as that is what we assume already.

htools: add some unittests for Types.hs
htools: rename Instance.auto_balance
… to autoBalance, per the recommended style.
htools: docstring fixes and improvements
No code changes (except one definition being moved around in QC.hs)are contained in this patch.

htools: fix prop_Node_rMem corner case
This patch fixes a bug in the test specification where we allowed nodeswith zero free memory (hence no instance can be added, at all) and addsa simple labeling of the way this test can fail.

htools: fix corner case in prop_Text_Load_Instance
This unittest had a corner case where it could fail if the sameprimary/secondary node names were generated.
htools: improve more unittests
Using new functionality in QuickCheck 2 (the suchThat function), wegenerate now better test cases, such that (heh) we have no longerincomplete tests.
htools: more fixes to unsatisfiable tests
Currently the way we generate nodes in some cases is by creating atotally random node, then restricting the test based on whether the node'size' (as defined by multiples of base unit) satifies some high/lowrules. This results in hard-to-satisfy conditions, so we change this...
htools: Rework some unittests
The new scaffolding which replaced the batch driver of QuickCheck 1 nowshows how many passes we have for incomplete tests. Some tests show verylow pass counts, so we rework them to have more actually valid testcases.
htools: Switch to QuickCheck 2.x
Since current distros don't package anymore QuickCheck 1.x, let's moveto 2.x.
This requires also a few changes to the code:
- Test.QuickCheck.Batch doesn't exist anymore, so we need to write some scaffolding code to replace it...
htools: some lint fixes
Removal of duplicate parantheses, removal of extra 'do', conversion fromnested if to guards, use hierarchical imports. All per hlint.
Add instance selection list to Loader.mergeData

Implement balancing with no instance moves
Note that --no-disk-moves and --no-instance-moves are not incompatible,but if both are used no solution can possibly exist.
Replace instance states hardcoded with constants
Add some tests for the auto_balance attribute
It tests node add/remove secondary, rather than cluster-level N+1checks, but it's better than nothing.

Read/write auto_balance via Text
This also means another change in the text format; we really shouldmove to json…
The unittests are also update for the new 9-column layout andadditionally a bit of improvement is done.
Add a new attribute to Instance.Instance
This will mirror Ganeti's be/auto_balance one, which we need to use toproperly match N+1 computations.
htools: Make opcode naming consistent with Ganeti codebase
This patch just cleans up the htools codebase to make it more consistentwith the naming of the Ganeti codebase.

htools: add an utility function for JSON parsing
This allows extracting values from a JSON object that might miss, buthave a well-defined default value.

htools: Use OpMigrateInstance with allow_failover option
Before hbal decided on the fly if an instance is migratable or not. Aswe implemented failover fallback in commit d5cafd31456 we can start touse that.

Another attempt at fixing htools build without curl
OK, my previous small fix was not good. There is another issue: haddoc(the documentation generator) needs to pass the same compiler options(i.e. in our case, -DNO_CURL) to ghc. But in case of no curl, then it...
Fix Haskell unittests without RAPI
Since we don't test for now the RAPI backend directly, we can simplyskip the import. Later we can make a conditional import if needed.
