Summary

When a user replaces or syncs their application with pruning enabled, there should be some feedback warning the user if their resources will be deleted.

Motivation

Currently, replace and "Sync with prune" can delete resources that no longer exist in Git, but there is no warning that this will cause resources to be deleted. This can cause accidental deletion of resources if a user isn't completely familiar with what they are doing.
