IMPALA-9256: Refactor constraint information into a separate class.
This change refactors the primary keys and foreign keys into a
SqlConstraints class since they are almost always used together. This
work also helps extend the constraints class to include other
constraints we may support in the future. (Ex: Unique constraints.)
This patch also:
- Fixes a bug in the MetadataOp.getPrimaryKeys() and getForeignKeys()
which returned incorrect results. The tests did not catch this
before beacuse we did not have tests to verify individual resultset
rows. The patch modifies these tests.
- Fixes a bug in foreign key constraint name generation that was
causing foreign keys corresponding to a composite primary key get
different foreign key constraint names instead of the same name.
- Introduces a canonical representation for foreign keys to prevent
bugs like IMPALA-9372 which can occur due to HMS returning results
in inconsistent ways.
Testing:
- Fixed the tests to work with the new behavior.
- Ran all the PK/FK tests.
