Hot Rod Java client docs updates

Purpose of this issue is to make sure all examples in Hot Rod Java client docs are up to date (do not document deprecated configuration like truststore path) and compile.

Also add details for Hot Rod URI for connections and start using tabbed examples for ConfigurationBuilder / Hot Rod client properties.

Docs currently show CacheContainer which doesn't compile as it's an interface from core. Need to go through code snippets in HR and update examples. Client docs really need more overhaul.
