This introduces JSON logging for Rails views saved to a file called
`development_json.log`, `production_json.log`, etc.
For example, instead of this unparsable log:
```
Started GET "/" for 127.0.0.1 at 2012-03-10 14:28:14 +0100
Processing by HomeController#index as HTML
Rendered text template within layouts/application (0.0ms)
Rendered layouts/_assets.html.erb (2.0ms)
Rendered layouts/_top.html.erb (2.6ms)
Rendered layouts/_about.html.erb (0.3ms)
Rendered layouts/_google_analytics.html.erb (0.4ms)
Completed 200 OK in 79ms (Views: 78.8ms | ActiveRecord: 0.0ms)
```
We get a single line with this:
```
{"method":"GET","path":"/,"format":"html","controller":"HomeController","action":"index","status":200,"duration":79,"view":78.8,"db":0.0,"location":"http://localhost/","time":"2017-07-18 09:35:17 -0700"}
```
