Redmine

The attached patch updates Rails environment files (development.rb, production.rb, and test.rb in config/environments directory) for Rails 6.1.

By updating the files, several useful new features in Rails 6.1 will be available (e.g. request_id in production.log, verbose_query_logs in development.log). Also, by looking at the commented out settings, the user can easily know what settings are available (e.g. config.force_ssl in config/environments/production.rb).
