> Catalog service should trigger events when it's state was changed.
> Other components should be able to subscribe on these events.
> Example:
> {code:java}
> CreateTableEvent = {TableDescriptor} // Contains tableId and parameter from CREATE TABLE command.
> AddColumnEvent = {tableId, ColumnDescriptor}
> {code}
> Maybe some additional info will be required, e.g. for finishing future if DDL operation was triggered locally.
> Note: Let's make these changes aside and avoid breaking the current implementation.
