Add 'Read' instances for most objects

This allows a cluster structure to be easily serialized via "read";
together with the already existing instances of Show, this gives a
poor man's serialization/deserialization implementation.

The patch also exports the compDetailedCV function from Cluster.hs, so...

Optimise the Luxi.recvMsg function

Since the current buffer cannot contain (during network reads) an EOM,
we should look for the EOM only in the newly-received string. While
this shouldn't make much difference, in some tests it cuts the recvMsg
total time by around half....

Complete the client Luxi implementation

All current Luxi calls are supported after this patch. A bug in
ArchiveJob is also fixed (Ganeti's job IDs are strings).

Add support for more LUXI calls

While not are directly useful, having them will open some possibilities
(e.g. polling for job changes in hbal's -X mode, and auto-archiving the
jobs once they are successful).

Change the Luxi operations structure

Currently, we define the LuxiOp type as a simple enumeration, and leave
the arguments structure to the users of the Ganeti.Luxi module. This is
suboptimal for a couple of reasons: first, we decouple the operation
type from operation arguments, and that means we don't use the type...

Replace fromJResult with annotateJResult

This patch removes all old uses of fromJResult with the annotated
version, and removes the non-annotated version. All JSON parsing points
should now have annotated errors.

Fix unused imports for ghc 6.12

GHC 6.12 has become more picky about unused imports, so we need to
remove/tighten some of them.

Change the Utils.fromObj signature

Currently the fromObj function takes a JSON object which is then
converted into a list of (String, JSValue) in which we make a lookup.
However, most of the callers of this function call it repeatedly on the
same object, which means we do the object→list conversion repeatedly....

More hlint fixes

This makes (for now) the code hlint-clean. This is per se not a huge
gain, but it allows easier tracking of regressions in style later
(one-two new violations are easier to diagnose when not hidden among 20
“known” ones).

Add two specialized Luxi calls

This are higher level wrappers over the basic callMethod.

Split the Luxi generic parts from the loader

The Luxi loader implements both a generic Ganeti Luxi client and the
loader; it is better if these two are separated. The patch adds a
Ganeti/Luxi.hs (not under HTools!) since that is generic for Ganeti, and
not related necessarily to htools.
