> Currently, as tables are stored as named list items in the Configuration, they are internally (to the configuration) identified by UUIDs. The same UUIDs are also used to identify tables in the whole system.
> We need to change the latter: that is, in addition to the internal IDs (needed only for configuration), we need to generate integer IDs and use them in the rest of the system to identify tables.
> For now, table IDs should be generated using same global counter that will be used to generate index and zone IDs.
> Internal IDs will remain until we switch from storing tables/indices/zones in the Configuration to storing them in the Catalog (this is out of scope of this task).
