Like ApprovalsUtil and ChangeMessagesUtil, we added an abstraction layer to assist in the migration to notedb. So far, we have only migrated published comments over to the notedb (drafts still are only stored in the reviewdb). This utility class helps to read published comments from either the notedb or the ReviewDb depending on the state of the NotesMigration instance. Additionally, in this change, I modified all callers of PatchLineCommentAccess that query for only published comments to instead use the corresponding methods in the PatchLineCommentsUtil. Finally, the test class, CommentsTest, had to be modified to add the ability to test reading published comments from the notedb, so I created a separate Config in that class to test the notedb path.
