Remove card priority when cleaning Sprint

[Ana06]

When executing cleanup-sprint the cards are moving to the backlog with the priority. It would be great to remove it automatically.

Often it's helpful to still have the priorities there after the cleanup so you can for example reestimate them and put them back into the backlog in the same order as before. So I would suggest to add this as an option --remove-priorities to the command.

I would do it the other way around, removing them automatically and have a command to keep priorities. 🤔

My rationale for requiring the user to explicitly call the option for removing the priority is that this is a destructive operation and that defaults should be non-destructive. There is no way to get the priorities back once they are removed so when the user has to add the option to remove them there are no surprises which can't be undone.

This has to be balanced with ease of use, though. The common case should usually be the default. I'm not clear what would be the common case here. We have two data points, your team which would remove them and my team which would probably keep them.

Another alternative would be to make the operation non-destructive for example by providing an undo feature. This probably would be overengineering in this case. But maybe there is a lightweight variant such as writing a log of the operations from where you can see what has been removed and you could restore it manually if needed.
