Understand how many image repositories are common

Context

I've heard anecdotally from users that they often have only one image repository per project (the root image). As we're considering making improvements to the Container Registry UI (for example Group Image Repositories by parent project in g... (#212283 - closed)) it would be good to understand how many container registry repositories are common per GitLab Project.

Desired end result

• 1 image repository = 30% of projects
• 2 image repositories = 2% of projects
• etc...
