Add request_id to RequestEndEvent

[davidpatters0n]

We'd like to trace back a request back to a particular request_id. To do this we'll need to pass the request_id to RequestEndEvent.

Example:

 @duration=0.02757700002985075,
 @http_status=200,
 @method=:get,
 @num_retries=0,
 @path="/v1/charges/ch_sp_sale_charge",
 @request_id='req_123',
 @user_data={}>

Questions

Will the request_id always be available? What about scenarios where a request fails?

Hello @davidpatters0n, this looks good! Will merge this shortly.

Will the request_id always be available? What about scenarios where a request fails?

The request id is generated from the Stripe server. No request id will exist on context if the response headers were not successfully received from Stripe, see here where the context is initted, without a request id, and then here where it is set from the response headers.

@richardm-stripe - I think a version bump is required.
