[Integration Tests] - Drop usage of unavailable docker image out of tests

[gaol]

Issue Overview

Docker image of jonmorehouse/ping-pong is wildly used in the tests, but I don't see it from docker hub or podman registries:

[🎩 lgao@lins-p1 arquillian-cube]$ docker pull jonmorehouse/ping-pong
Using default tag: latest
Error response from daemon: pull access denied for jonmorehouse/ping-pong, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

Unless I did something wrong, the image gets missing.

I found a hashicorp/http-echo image which has the same function so we may consider to use that for the tests.
