> 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.
