Lettuce-6.0 module - See if we can add the database "name" (number) to the external call and improve fetching the RedisURI instance

[jtduffy]

Description

In the lettuce module we explicitly call noDatabaseName() when creating the external params.

In the Jedis module, we do have access to the database name (which in Redis is an integer) and add it to the external params.

We need to investigate the Lettuce driver and see if this info is available to us to add to the lettuce external datastore params call.
