Tracking Details

• json schema used in gitlab-experiment tracking.
• Due to data tooling limitations, we should only utilize category, action and label. i.e. try to keep from using property and value. Be aware if adding the experiment context to existing events that use property or value that some concessions will need to be made in order for it to show up in the experiment dashboard.
