more visual feedback to understand task size

[tylerflex]

A user might unknowingly submit a simulation that is much larger or smaller than expected. Currently we print some info about the FC cost, but I think some visual indication of the task size could be useful. For example, displaying the progress bar in blue, green, yellow, orange, red, determined by the size.

This is an open ended ticket, but we should improve our UX to make it more intuitive so users know how large of simulations they are running, to avoid confusion.
