Add table constraint add/modify/remove logic #97

Closed paupino closed 6 years ago

paupino commented 6 years ago

Added table constraints to supported delta's. Modification currently does a DROP/ADD since ALTER is only supported after 9.4 for a subset of operations. #89 should be evaluated before looking into optimizing this. In addition, a follow up PR will come in #96 to help control these statements better.
