max (max) steps - 50,000

What if a person specifies 10,000,000 steps? Let's have a realistic limit. 50,000 is good enough - 20,000 is the "normal" max steps.

@johnml1135 If the user specifies a number of steps larger than the max amount of steps, should we fail the job and give them a chance to reenter a max steps that is under the limit? Or should we just automatically change it to the upper limit of 50000 while logging a warning without failing? The second option would be a smoother experience, although it wouldn't be as transparent to the user since I'm not sure that users will be able to see warning logs in machine.py.

We should throw an error if they are over the limit.
