The functions which prepare schema change mutations (such as `prepare_new_column_family_announcement`) would use internally generated timestamps for these mutations. When schema changes are managed by group 0 we want to ensure that timestamps of mutations applied through Raft are monotonic. We will generate these timestamps at call sites and pass them into the `prepare_` functions. This commit prepares the APIs.
