make list jobs parallelized

[mnikhil-git]

Hi @ryukobayashi

I see currently the listJobs method gets the list of jobs and process them sequentially in a for loop. Is it possible to make it parallelized by using threads? so faster responses can be had at the rest client.

Also, I see when I use /job/detail/, the corresponding method iterates over the list of running jobs until the job id is matched and the details of the job are fetched -- this kind of slows down the operations for client sometimes, it is perhaps okay to just get the jobstatus of given job id and then get the details if the jobid is genuine?

thanks.

@mnikhil-git hm, I see. maybe, I think that it can be a thread.
