Improve "clean old history" command to considering the number of entries

[rodrigobraga]

Problem Statement

I want to keep the history for some models clean based on number of entries.

Describe the solution you'd like

Add an argument to "clean old history" command, to keep just a specified number of entries regardless of age.

Describe alternatives you've considered

Querying history ignoring the latest five (for exemple) entries, then deleting all the rest.

Additional context

Not applicable.

Thinking about this, I have two suggestions, detailed below:

New command

A new command splitting the clean old history between clean by time and clean by counting, avoiding conditionals to deal with both in same command.

Current command maybe can be marked as deprecated and turn into an alias to new command (by time).

---

New parameter in the current command

Add a new parameter (called "keep" for example) and inside _proccess we can slicing the queryset to ignore entries beyond the limit.

---

Are they options interesting?

Personally I think the first can more concise.
