Review GitServer implementation

[fabiobrz]

Issue Overview

Arquillian Cube GitServer.java is now using Gitea.
This causes issues with the project CI checks that use CRC and often fail at deploying the Gitea operator.

Expected Behaviour

The HelloPodDeploymentOpenShiftITCase should be executed by the project CI and pass

Current Behaviour

The HelloPodDeploymentOpenShiftITCase is skipped

Steps To Reproduce

1. Just have a look to one execution of e2e CI checks

Additional Information

The logic that the test uses could be fully revisited, thus removing the need for a remote Git service integration

Resolved the issue with HelloPodDeploymentOpenShiftITCase; the fix involved dropping the Gitea dependency. See PR #1411
