Split 'routes.rb' file into multiple small files

[aitbw]

Where

• Related Issue: Break down routes.rb into smaller files and allow custom routes easily #1852

This PR closes #1852 once merged

What

• Split down routes.rb file into multiple small files to make the application's routes more manageable and easier to customize.

How

• Took inspiration from the work done @ GitLab CE and this article written by Michael Cho.

The routes that took the most lines on the routes.rb file were separated into their own file under config/routes. An initializer called routing.rb under config/initializers was created to load all the isolated routing files.

Warnings

• Since this PR rewrites most of the routes.rb file, precaution is advised when merging this commit into a Consul fork with custom routes. If necessary, custom routes can be easily isolated into their own files creating a new file under config/routes/your_custom_routes_file.rb, then appending to the routes.rb file the following: draw :your_custom_routes_file
