> Currently, drill will get all the storage-engine-specific rules in StoragePluginRegistry,
and register all the rules (HBase, Hive, etc) with the optimizer planner.  This means even
the query only refers a Hive table, the optimizer may still have rule for other storage-engine.
> In stead, we should register the storage-engine-specific rules using interface RelNode's
register() method, when we know a scan is for one particular storage-engine.  This will avoid
the issue that optimizer has more than necessary rules in its rule queue.
