## Description Add functions to Collection and Stream interfaces that allow for getting more information about the difference between the previous backup and the currently in-progress one. These will allow delta token-based incremental backups to determine how the state has evolved. Current code does not use these functions and return values for them are "default" values that should result in full backups even if KopiaWrapper is updated to start checking the values and GraphConnector still pulls all items These functions are not used during restore and can return "default" values ## Type of change <!--- Please check the type of change your PR introduces: ---> - [x] 🌻 Feature - [ ] 🐛 Bugfix - [ ] 🗺️ Documentation - [ ] 🤖 Test - [ ] 💻 CI/Deployment - [ ] 🐹 Trivial/Minor ## Issue(s) * #1700 ## Test Plan <!-- How will this be tested prior to merging.--> - [ ] 💪 Manual - [x] ⚡ Unit test - [ ] 💚 E2E
