Describe the solution you'd like
Instead of just adding a force-option, it would make sense to add a push_options-input. User could then write their own logic which will then be passed to the git push command.

Describe alternatives you've considered
None

Additional context
In the README, we would have to make clear, that using git push --force can be dangerous.
