Test Kubernetes Composer

[samuelbernardolip]

First step would be to test the Kubernetes Objects deployment from official examples:

• Declarative Management of Kubernetes Objects Using Configuration Files
• Declarative Management of Kubernetes Objects Using Kustomize

The repository is a fork: https://github.com/EOSC-synergy/JePL-k8s-test

Add github workflow to keep continuous integration testing with newer releases of kubernetes:

• [Sync fork]{https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/syncing-a-fork}
• Fork Sync Action
