Support integration with MapR-DB (MapR 5.2.x, 6.x)

As a user of Teiid, I need to be able to reference MapR-DB as a datasource to incorporate full data content into Teiid (VDB).

To accept, at a minimum, data read, support should be based on (at least) the current 6.x release. Ideally full RUD support would be available.
