Add a new column base_table to the system.tablets table. It can be set to point to another table to indicate that the tablets of this table are co-located with the tablets of the base table. When it's set, we don't store other tablet information in system.tablets and in the in-memory tablet map object for this table, and we need to refer instead to the base table tablet information. The method get_tablet_map always returns the base tablet map.
