partitioned foreign tables are not created automatically

- Created a partitioned table pt(a int, b int, c int);
- Distributed pt on ‘a’ using create_distributed_table
- Create a table pt_a, partition of pt for some values → pt_a is automatically distributed
- Create a cstore table pt_c, partition of pt for some other values → pt_c is created but not distributed
Expect
- pt_c is either distributed or an error is throw

```sql
create table pt(a int, b int, c int) partition by range (a);
select create_distributed_table('pt', 'a');
create table pt_a partition of pt for values from (1) to (100);
-- verify table is distributed and shards are created
create foreign table pt_c partition of pt for
values from (100) to (1000) server cstore_server options (compression 'pglz');
-- pt_c is not distributed nor shards are created
select create_distributed_table('pt_c', 'a');
-- pt_c is now distributed
```

We should intervene and throw an error when a partitioned foreign table is created on distributed partitioned table until we support this.
