Title: Added CREATE/DROP CONSTRAINT syntax in Cypher

o Create contraint syntax, for example:
CREATE CONSTRAINT ON (foo:Foo) ASSERT foo.name IS UNIQUE
o Drop constraint syntax, for example:
DROP CONSTRAINT ON (foo:Foo) ASSERT foo.name IS UNIQUE
o Doesn't actually do anything, just able to parse it.
