Integration tests global refactoring

We should done some work on integration tests so that we can rely on them to improve our code quality and reduce the technical debt.
A sprint will be dedicated.
Here are the tasks we should work on:

• run tests from Maven and document how to run them if specific steps are required
• If failure, fix the failed tests
• Refactor / move tests to the components repository
• Fix/make sure tests are run in PR check

This huge task should be done component per component. Sub-tasks JIRA will be created for each component.
