Describe the solution you'd like Please add the number of found (scenarios|collections|bouncers), if i run cscli (scenarios|collections|bouncers) list

This would make a quick compare e.g. between servers much more easier instead of counting.

Example of what you imagine At the first line after the list command you write in uppercase eg. COLLECTIONS, so extend this by (found: 6) or sometimes else which makes sense.
