[v3] Add key features

[ErikSchierboom]

This issue is part of the migration to v3. You can read full details about the various changes here.

In Exercism v3, each track must specify exactly six "key features". Exercism uses these features to highlight the most interesting, unique or "best" features of a language to a student.

Key features are specified in the top-level "key_features" field in the track's config.json file and are defined as an array of objects, as specified in the spec.

Goal

The "key_features" field in the config.json file should be updated to describe the six "key features" of this track. See the spec.

Example

{
  "key_features": [
    {
      "icon": "features-oop",
      "title": "Modern",
      "content": "C# is a modern, fast-evolving language."
    },
    {
      "icon": "features-strongly-typed",
      "title": "Cross-platform",
      "content": "C# runs on almost any platform and chipset."
    },
    {
      "icon": "features-functional",
      "title": "Multi-paradigm",
      "content": "C# is primarily an object-oriented language, but also has lots of functional features."
    },
    {
      "icon": "features-lazy",
      "title": "General purpose",
      "content": "C# can be used for a wide variety of workloads, like websites, console applications, and even games."
    },
    {
      "icon": "features-declarative",
      "title": "Tooling",
      "content": "C# has excellent tooling, with linting and advanced refactoring options built-in."
    },
    {
      "icon": "features-generic",
      "title": "Documentation",
      "content": "Documentation is excellent and exhaustive, making it easy to get started with C#."
    }
  ]
}

The text is ready, but we're missing icons.

[ErikSchierboom]

Correct. We still have to compile the list, but we'll do that many tracks have defined their key features. Feel free to close this if you like, whatever you prefer.

[angelikatyborska]

Let's keep this issue open until all the icons are defined and Elixir has chosen theirs.
