Add Maven Plugin for Grammar Extension

This change introduces a new asterix maven plugin for grammar
extension. The plugin takes a base grammar file and an extension
file and combine them to generate an extended grammar. A base
grammar can be extended by overriding production nodes, adding
extending existing nodes, or introducing new terminals and
non terminals.

In addition, a mvn verify goal was added to generate the parser
java files from the grammar generated by the test.
