When starting the Luxi daemon, check if it's able to fork

If a Haskell program is compiled with -threaded, then inheriting open
file descriptors doesn't work, which breaks our job death detection
mechanism. (And on older GHC versions even forking doesn't work.)...

Make luxid aware of SIGCHLD

As luxid forks off processes now, it may receive SIGCHLD
signals. Hence add a handler for this. Since we obtain the
success of the child from the job file, ignoring is good
enough.

Execute jobs as processes from Luxi

.. instead of just letting the master daemon to handle them.

We try to start all given jobs independently and requeue those that
failed.

Add a function for failing a queued job

.. which will be used if the Luxi daemon attempts to start a job, but
fails.

Add optional fields for job livelocks and process IDs

This will allow to check if a particular job is alive, and send signals
to it when it's running.

The fields aren't serialized, if missing, for backwards compatibility.

Add Haskell and Python modules for running jobs as processes

They will be used by Luxi daemon to spawn jobs as separate processes.

The communication protocol between the Luxi daemon and a spawned process
is described in the documentation of module Ganeti.Query.Exec....

Add an utility function for writing and replicating a job

Use the function where appropriate.

Also handling of CancelJob is slightly refactored to use ResultT, which
is used by the new function.

Add a livelock file for the Luxi daemon

The file is initialized and kept within JQStatus.
It is temporarily assigned to jobs spawned by Luxi until they create
their own livelock files.

Move `isDead` from DeathDetection to Utils/Livelock

.. as it has nothing special to do with WConfd and fits the new module
better.
