Provide an option to virtualize source exceptions

Currently we'll pass the source exception along with the Teiid exception. And from source sql exceptions we'll also rely the sql state/code. When connecting to databases of different types it would be best to return a common set of codes.

There is exception mapping logic in Hibernate that we could reuse, but this could apply to the non-jdbc sources such that a predictable code will seen by Teiid clients.
