Add support for hypertable constraints
This PR add support for primary-key, foreign-key, unique, and exclusion constraints. Previously supported are CHECK and NOT NULL constraints. Now, foreign key constraints where a hypertable references a plain table is support (while vice versa, with a plain table references a hypertable, is still not).
