Cover MQTT API with black box tests

+
+## Black box tests execution
+To run the black box tests with using Docker, the local Docker images of Thingsboard's microservices should be built. <br />
+- Build the local Docker images in the directory with the Thingsboard's main [pom.xml](./../../pom.xml):
+        
+        mvn clean install -Ddockerfile.skip=false
+- Verify that the new local images were built: 
+
+        docker image ls
+As result, in REPOSITORY column, next images should be present:
+        
+        thingsboard/tb-coap-transport
+        thingsboard/tb-http-transport
+        thingsboard/tb-mqtt-transport
+        thingsboard/tb-node
+        thingsboard/tb-web-ui
+        thingsboard/tb-js-executor
+
+- Run the black box tests in the [msa/black-box-tests](../black-box-tests) directory:
+
+        mvn clean install -DblackBoxTests.skip=false
