Allow param type definition in route_param

ref #1009
I'd like to use type definition in route_param, so I implemented it by using requires DSL.

Very nice thanks.

Great feature, unfortunately this breaks with grape_logging middleware, due to nil value for Response object which is required here. Nevertheless, the fact that response is nil, should be solved in grape. Any idea why this happens?

In a very simplified version, my migration looks like:

params do
  requires :id, type: Integer
end
get '/:id' do
  params.to_json
end

route_param :id, type: Integer do
  get do
    params.to_json
  end
end

@rngtng Could you provide a minimal failing project with Gemfile.lock?

@namusyaka thx for you quick response. while creating an example project i figured it actually hasn't anything todo with the refactoring to route_param, but with upgrading to grape HEAD. This pulled in
#1240 which call after on logging https://github.com/aserafin/grape_logging/blob/master/lib/grape_logging/middleware/request_logger.rb#L18. let's continue discussion on #1240
