      Description

      Currently, if the filter pushdown is impossible (which is most cases), the client gets all partition names from metastore, filters them, and asks for partitions by names for the filtered set.

      Metastore server code should do that instead; it should check if pushdown is possible and do it if so; otherwise it should do name-based filtering.

      Saves the roundtrip with all partition names from the server to client, and also removes the need to have pushdown viability checking on both sides.
