### What changes were proposed in this pull request?
Fix DESCRIBE FORMATTED for STRUCT datatype columns output
### Why are the changes needed?
Currently, when we have a table with STRUCT datatype column, running the
DESCRIBE FORMATTED query on the particular STRUCT column produces wrong output,
For Exm:
`CREATE TABLE tbl_t (id int, point STRUCT<x:INT, y:INT>);
DESCRIBE FORMATTED tbl_t point;`
gives the following output:
`+------------------------+----------------------------------------------------+
| column_property | value
|
+------------------------+----------------------------------------------------+
| col_name | x
|
| data_type | int
|
| min |
|
| max |
|
| num_nulls |
|
| distinct_count |
|
| avg_col_len |
|
| max_col_len |
|
| num_trues |
|
| num_falses |
|
| bit_vector |
|
| comment | from deserializer
|
| COLUMN_STATS_ACCURATE |
{\"BASIC_STATS\":\"true\",\"COLUMN_STATS\":{\"id\":\"true\"}} |
+------------------------+----------------------------------------------------+
`
Here as we can observe that the col_name & data_type are wrong & instead
should be point & struct<x:int,y:int> respectively.
