Add structured logging for Rails processes 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"} ``` Part of #20060 2017-07-17 18:54:13 -04:00			`---`
