docs: Getter for all YAML settings.
  Example: `settings.getAll().then(...)`
  will return an Object like this (assuming we're supporting `routes`
  and `globals`):
  {
  routes: {
  routes: null,
  collections: { '/': [Object] },
  resources: { tag: '/tag/{slug}/', author: '/author/{slug}/' }
  },
  globals: {
  config: { url: 'testblog.com' }
  }
  }
  @returns {Object} settingsObject
  @description Returns all settings object as defined per YAML files in
  `/content/settings` directory.
