title: How to update list of entities in Room
body: <p>I have API request which gives me a list of entities. I want to update my database by adding(updating) items and deleting the missing ones (which are not included in the response, but included in database). I'm adding and updating data by <code>@Insert(onConflict = OnConflictStrategy.REPLACE)</code>. I know, that i can delete missing items manually, by checking each item individually, but can't figure out is there any kind of Room-related solutions for this case.</p>
