Each application should have the example JSON file which will allow to test deployment of this application automatically.

We have many Murano applications in the repository https://github.com/murano-project/murano-app-incubator and we can't automatically test all of them (at least new) because we need to manually generate JSON file which is the custom for each application and it is not ewsy to generate the right JSON file automatically for each application.

We can create such JSON file for each application manually once, store this file in the folder with this application and after that use these JSON files to automatically test each application for each commit. When we will add new application, we will need to write the JSON file for this application too, and new application will be automatically tested with this JSON.

This JSON file should contain:
1. Example of JSON which we should send to Murano to deploy the application
2. List of ports which we should check after the deployment. If these ports are not listened, deployment finished with errors.
3. Timeout for the deployment of this application.
