[LRUG] VCR caches

[Stuart Harrison]

VCR offers support for this with the `filter_sensitive_data` option. I tend
to loop through all of my env vars as filter them all out like so:

```
dotenv = Rails.root.join('.env')
filter_vars = File.exist?(dotenv) ? Dotenv::Environment.new(dotenv, false)
: ENV


VCR.configure do |c|
  filter_vars.each do |key, value|
    c.filter_sensitive_data("<#{key}>") { value }
  end
end
```

This way, any credentials you have in your .env file (assuming you’re using
dotenv) automatically get filtered out.

As it happens VCR cassettes accept ERB tags.

So I once wrote a script to regenerate cassettes using real credentials,
then right afterwards replace the credentials in the cassettes with an ERB
reference.

It's risky that you'll mess it up,
but it worked for my needs.
