Add the number of pipeline run

[sylhare]

As of now, we look into the first page of pipeline (100 pipelines max). Then we check when they run. A nice feature would be to know the amount of pipeline run so we could see:

• a few number of pipeline in a sprint could explain some success stat
• a normal number of pipeline to see our average per sprint
• a hundred number of pipeline, which means we would need to add the feature to look into more pages.
