Delete a job, based on its identifier.
Return the identifier of the highest-priority job waiting to run.
Return a list of all jobs in the queue, ordered from top priority to least priority.
Return the number of jobs that are waiting in the queue.
a) Write the RESTful API endpoint definition of the above functionality.
