This adds queueing support for requests that requires a response making it simpler to use the API. The storage is keep in the parameters of the request so it is up to the application to define how many can be queued but in case the application don't want a request to block waiting for a buffer it can use BLUETOOTH_ATT_REQ_COUNT to control the available buffers which is recommended in case the requests will be sent from the RX fiber.
