Deploy a web app on a dedicated server with Kamal
This gist is still a draft. At the moment it is not functional: see basecamp/kamal#257

What the hell, I'll even host my private container registry on it.

| # Evaluates a sample of keys/values from each redis database, computing statistics for each key pattern: | |
| # keys: number of keys matching the given pattern | |
| # size: approximation of the associated memory occupied (based on size/length of value) | |
