Manually Edit AWS Console "Switch Role" Configuration in Bash

Motivation

At Gruntwork, we work with multiple software teams. That means we have to modify the "Switch Role" history multiple times. But the only way to do that today is to delete your cookie and clear all AWS Console saved settings. That got old after a while, so these instructions enable you to modify the "Switch Roles" configuration directly.
