What are you trying to achieve or the steps to reproduce?

Trying to create routes using a default route validator

  {
    method: 'POST',
    path: '/cookie-settings',
    options: {
      auth: false,
      validate: {
        payload: {
          usage: Joi.string().valid('true', 'false').required(),
          campaigns: Joi.string().valid('true', 'false').required(),
          settings: Joi.string().valid('true', 'false').required(),
          redirectLink: Joi.string().allow('').optional()
        },
        failAction: handler.cookieSettingsHandler.postFail
      }
    },
    handler: handler.cookieSettingsHandler.post
  }

What was the result you got?

Error: Cannot set uncompiled validation rules without configuring a validator Doesn't seem like there's a way to set a default validator to glue

What result did you expect?

Expect to be able to pass Glue to instantiate hapi with a default validator [This](https://hapi.dev/api/?v=19.1.1#server.validator()) example of using hapi directly shows setting the validator after the server has been created, but glue creates the server and tries to attach routes without the chance to specify the validator.
