Refactor GlRepository to include suffix
What does this MR do?
In !21739 (merged) we're adding repositories to snippets. The repository disk path won't include any suffix but GlRepository automatically adds it unless it is a project one.
In this MR we add suffix to the repo type and when it is present we'll add the suffix to the disk path. We also refactor some parts of these classes to adapt them to the new naming replacing subject to container.
Does this MR meet the acceptance criteria?
