Kamil Braun a664ac7ba5 treewide: require group0_guard when performing schema changes
`announce` now takes a `group0_guard` by value. `group0_guard` can only
be obtained through `migration_manager::start_group0_operation` and
moved, it cannot be constructed outside `migration_manager`.

The guard will be a method of ensuring linearizability for group 0
operations.
