Support Rails “production” environment within the GDK context. Enables more accurate performance profiling.

Performance Profiling for GitLab GDK

GitLab GDK defaults to the Rails 'development' environment.

For real-time profiling, it is desirable to have Rails use the 'production' environment to allow classes to be cached, queries to be cached, and to allow Rack to avoid re-validating its entire stack for each incoming request.

The GDK allows simulation of a production Rails environment by setting the contents of the .gdk_environment file to production

    echo production > .gdk_environment
    gdk reconfigure
