CDC tables use a custom partitioner, which is not reflected in schema
dumps (`CREATE TABLE ...`) and currently it is not possible to fix this
properly, as we have no syntax to set the partitioner for a table.
To work around this, the schema loader determines whether a table is a
cdc table based on its name (does it end with `_scylla_cdc_table`) and
sets the partitioner manually if it is the case.
