Better support chrome headless downloads with parallel builds #67
Description
Currently, a number of projects rely on on downstream tweaks to configure the:chrome_headless driver to be able to download files on chromedriver versions 77+ on Linux.
There are also downstream configurations to generate a separate download directory per test process, so race conditions do not occur when using Rails 6 parallel testing.
We should look to clean this logic up, and include by default in ndr_dev_support.
