Executes the next job in the Work Queue
by passing it to the callback function.

If that results in a {@see \RuntimeException},
the method will try to re-queue the job
and re-throw the exception.

If the execution results in any other {@see \Throwable},
no re-queueing will be attempted;
the job will be buried immediately.

If the next job in the Work Queue is expired,
it will be silently deleted.

@param string|string[] $workQueue See {@see WorkServerAdapter::getNextJob()}.
@param callable $callback         The handler callback to execute each Job.
Expected signature: <tt>function(Job): ?int|void</tt>.
See {@see JobResult} for possible return values.
@param int $timeout               See {@see WorkServerAdapter::getNextJob()}.
@throws \Throwable  Will re-throw on any Exceptions/Throwables from the <tt>$callback</tt>.
@throws \UnexpectedValueException  in case of an unexpected callback return value (should be a {@see JobResult} constant or NULL or void).
