Simplify 'GetMasterInfo' RPC

RPC 'GetMasterInfo' returns several fields, namely, 'master_netdev',
'master_ip', 'master_netmask', 'master_node', and 'primary_ip_family',
of which only the 'master_node' is actually used.

In this patch:
  • remove all the other fields and keep only the 'master_node' field....

Implement job cancellation in luxid

As luxid handles the job queue, this daemon is the natural
place to handle job cancellation. Answering to CancelJob requests
is also necessary for luxid to be feature compliant with masterd,
even for command-line requests only....

Provide a function to compute the canceled version of a job

When a job gets canceled while still queued, dequeuing requires
luxid to mark it as cancelled. So provide the necessary pure
function to do so.

Support canceling dequeued jobs

Even after jobs have been handed over for execution, it might
still be possible to cancel them. On such case would be the
job still waiting for a lock. Eventually, we will have to
communicate to the job directly, but as long as execution is...

Add dequeuing to the job scheduler

This only removes queued jobs from the queue
and indicates whether the job was found in the queue.
For jobs that are already started from the queue's
point of view, it might still be possible to cancel
them, e.g., if they are still waiting for locks....
