SQL++ parser:
1. refactored asterix-aql to become asterix-lang-common and asterix-lang-aql, where the former is the common part for different languages;
2. added asterix-lang-sqlpp on top of asterix-lang-common;
3. ported parser tests, optimizer tests and runtime tests in asterix-app to their sql++ version, and added parser tests for all the queries.
