Arvados

I made a slight change in my 7GiB docker image file and I used arv keep docker to put it into keep, which took 20 minutes. Afterwards, I re-ran the job using the docker image and it takes 7 minutes for the job to start running. I feel like a half hour turn-around time is really long. I definitely could make my image more lightweight but the 7 minutes to load the image to the job is still long.
