Enable VCR cassette recording and update existing cassettes

[johnpaulashenfelter]

A lot of our VCR cassettes are old -- as in years. Some examples popped up in

One of the impediments to re-running them is the areas where connectivity is and isn't allowed, even from staging. Without access from staging, there's pretty much no way to update a cassette (which begs the question about how they were recorded in the first place).

There's a couple of possible solutions to this:

• [ ] Enable access in the appropriate environments
• [ ] Anoint a handful of people with access to rerun cassettes in production and sanitize
• [ ] Start moving to a mock api so developers can control the access

None are perfect, but all are better than cassettes that may or may not reflect current reality.

@johnpaulashenfelter Is this something that we still want to do? If so, can you please remove the Product Support label and add the appropriate one?
