[Mongodb] merge adds Async mongodb driver, update normal driver to talk to mongo 2 and 3 clusters.

Add autoflush property to HBaseClient

to the 3.0 driver from MongoDB Inc. and updated to the new Document and
fluent APIs.

URI to configure the client. Old properties are deprecated and but will
be added to the URI if present and the URI does not already contain a
