(feature) path parameters in yaml

[nahelbahel]

Right now, it is not possible to pass a YAML description of path parameters for routes. Like

module.exports = {
  // parameters for all operations in this path
  parameters: `
    - in: path
      name: id
      required: true
      type: integer
  `
}

This would be quite handy, to be consistent when also writing the apiDoc in YAML
