IMPALA-8291: Show constraints in DESCRIBE FORMATTED
Support for displaying primary and foreign key constraints in describe
formatted output. The output attempts to be as close to Hive's
implementation as possible.
Also includes constraint definitions for the TPC-DS test workload.
Testing:
* Fresh load of testdata
* Metadata query tests comparing the output between Impala and Hive

> Currently, DESCRIBE EXTENDED table_name command does not display constraint
