Change subject: IMPALA-9903: Reduce Kudu openTable calls per query
......................................................................


Patch Set 2:

Some of these table objects will have longer than query lifetime.

LocalKuduTable is per-query, but the other classes can live for longer in the 
catalogd cache or the legacy impalad catalog cache (i.e. when 
--use_local_catalog=false). Not sure if that's safe or not - I think it could 
affect behaviour if the Kudu schema changes in the meantime, no?
