It would sometimes be useful to gather generic information about the shape of a table or database. I'm thinking of something similar to the wt verify dump_pages but with all of the information redacted.

Ideally we would be able to find out:

• Tree depth
• Internal page sizes
• Leaf page sizes
• Key count and size
• Value count and size

Ideally the format would be quite compact, so a table that is hundreds of GBs generates a reasonably sized "dump" file, which could then be retrieved and analyzed.
