> Currently, get_partition_names returns the partition names in an escaped form  ie 'ds=2010-02-03/ts=2010-02-03
18%3A49%3A26/offset=0-3184760670135/instance=nfs/host=nfs'. In this case, the colons have
been replaced by %3A. The escaped form is necessary because the partition column values could
contain symbols such as '=' or '/' that would interfere with parsing or have some other unwanted
effects. See HIVE-883.
> However, there is no way to directly retrieve the partition using the escaped name because
get_partition accepts a List<String> that requires the partition column values to be
in their original unescaped form. So the proposal is to add get_partition_by_name() that directly
accepts the partition name in the escaped form.
