Since luxid is going to write to the job queue,
it needs to honor drains of the queue as well.

Add Luxi Request to pick up a job in the queue

During the transition to the new daemon layout, from step 2
onwards, luxid will write to the queue but masterd will trigger
the execution. Therefore, add a new luxi request to tell masterd
to pick up a job that has already been written to the queue....

Provide means of locking a file

Two avoid two processes simultaneously accessing the same
on-file structure, like the job queue, file locks are used.
Therefore, provide this functionality in Haskell as well.

Provide path to the queue lock file

To avoid several processes accessing the queue at the same time,
Ganeti locks the queue via a lock file on disk. Provide the path
to this file.

Provide a function to write jobs to disk

This function writes a (non-archived) job to disk. The file
name can be computed from the job id, which is part of the job.

Provide means to allocate new job ids

Add utility functions to allocate new job ids by increasing
the value stored in the serial file. As this function is
used in a multi-threaded program, synchronize access over
an internal lock.

Add function to get master candidates from configuration

With luxi daemon taking over part of the job queue management, it will
also be responsible for replicating the queue to all master candidates.
Therefore, add a function to extract the list of master candidates from...

Support RPC asking to replicate part of the job queue

To be able to replicate the job queue, in particular the serial,
luxid needs to be able to send the jobqueue_update RPC. So add
its definition.

Provide function to obtain the unique element of a list

This version of 'the' properly lives in the 'Result' monad,
as opposed to traditional one calling 'error'. The reason
why it is 'Bad' that not precisely one element is returned
