Using with YAML

The keyword args in the alert method work well with YAML symbol keys, and can be mixed with existing YAML-based build configurations if desired.

Given a config like:

---
dev:
    :alert:
        :banner: Development
        :description: |
            You are deploying to the dev environment
            outside the CI pipleine.
        :color: :yellow
prod:
    :alert:
        :banner: Production
        :description: |
            DANGER! You are deploying directly to
            production outside the CI pipeline. This
            is highly unusual and dangerous!
        :color: :red

The args for alert can be passed like:

Klaxon.alert YAML.load_file('config.yml').dig ENV['ENV'], :alert do
   # deploy files...
end
