hail: add an extra safety check in relocate

If we select the primary as new secondary, better to fail than return
wrong data to Ganeti.

Revert deprecation of evacuate mode in hail

As discussed offline, the new node-change mode could be used for
evacuation, but it's not directly useful as it returns a list of
opcodes; therefore, we need to partially revert commits fbe5fcf and
5b53ca7 that removed it (and multi-evacuate, which remains removed)....

htools: rework the algorithm for ChangeAll mode

I think I've identified the problem with the current ChangeAll
mode. The current algorithm works as follows:

- identify a new primary by choosing the node which gives best score
as new secondary
- failover to it...

htools: replace two hardcoded uses of pri+sec nodes

These two cases use explicit uses of primary and secondary nodes with
Instance.allNodes, which means the code is more flexible if the
internal layout of the instance changes.

I've verified that the output of involvedNodes is not required to be...

… and failover too. Not many changes otherwise except for

htools: add more functions for local disk storage

These will be used in Node.hs for proper add/remove instance
code. Furthermore, we restrict the movable status to the right disk
templates only, so that we don't attempt to move the 'wrong' instance

htools: add two more small unittests

This adds tests for the opToResult and eitherToResult functions from
Types.hs, and changes two other tests for the same module to test JSON
serialisation (which automatically also tests the lower-level to/from
string conversion functions)....

Tested only on GHC 7.x, will test on 6.1x too before commit.

htools: further docstring fixes

This adds parameter documentation for Cluster.iMoveToJob (I think it
was not clear if the new or old node list is needed) and fixes other
docstring style issues.

After this patch, all modules except for CLI.hs (which has many...
