Update MQTT config for Keep Alive demo that uses dummy timer (#457)

Browse Source 
The MQTT library has been updated with the MQTT_RECV_POLLING_TIMEOUT_MS and MQTT_SEND_RETRY_TIMEOUT_MS configurations which should be set to zero when using a dummy timer function to avoid possibility of infinite loop when retrying failed transport send/receive calls. As the MQTT Keep Alive demo uses a dummy timer function, this PR updates the demo configuration to set these timeouts to zero.
