Exit cleanly on renderer crashes and provide an explanation and ramifications

[brian-mann]

It is possible that when running headlessly the renderer crashes. This can be due to a bunch of reasons:

• memory leaks in Cypress
• running in a memory starved VM environment
• running lots of tests on an extremely memory intense application
• GPU driver conflicts with Chromium
• your code created an endless loop
• browser bugs with Chromium

It is therefore impossible to prevent and we must take this into account how to recover.

Currently Cypress exits with a 0 status code which is very, very, very wrong.

The simple fix for this is to add an error explanation, link to an error doc, and exit with a non 0 status.

We also need to finish the underlying cleanup process such as compressing videos, uploading assets, report on this error, etc.

Going to go with something like this...

Fixed in 0.18.3.
