mosquitto-clients binary package in openKylin Nile V2.0 arm64

 This is two MQTT version 5.0/3.1.1/3.1 command line clients. mosquitto_pub can
 be used to publish messages to a broker and mosquitto_sub can be used to
 subscribe to a topic to receive messages.
 .
 MQTT provides a method of carrying out messaging using a publish/subscribe
 model. It is lightweight, both in terms of bandwidth usage and ease of
 implementation. This makes it particularly useful at the edge of the network
 where a sensor or other simple device may be implemented using an arduino for
 example.
