DATAJPA-180 - Added support for StartingWith, EndingWith, Containing to query creator.

The query derivation mechanism now supports StartingWith, EndingWith and Containing as keywords using the Criteria API's like predicate and massaging the given parameters accordingly. Refactored parameter binding  for CriteriaQuery instances to encapsulate the knowledge of how to massage a parameter based on the type.
