norbert.luksa 288c8c41b5 IMPALA-8755: Frontend support for Z-ordering 
Extended the SQL grammar with an optional and a default flag for
SORT BY, namely ZORDER and LEXICAL. If set, the new 'sort.algorithm'
table property will be set to ZORDER and the information will sink
down to the backend. The default order is indicated by LEXICAL
and can be omitted. Examples are:

CREATE TABLE t (a INT, b INT) PARTITIONED BY (c INT)
  SORT BY ZORDER (a, b);
CREATE TABLE t SORT BY ZORDER (int_col,id) LIKE u;
CREATE TABLE t LIKE PARQUET '/foo' SORT BY ZORDER (id,zip);

ALTER TABLE t SORT BY ZORDER (int_col,id);

The following two are the same statements:
CREATE TABLE t (a INT, b INT) SORT BY (a, b);
CREATE TABLE t (a INT, b INT) SORT BY LEXICAL (a, b);

For strings, varchars, floats and doubles Z-ordering is currently
not supported. It's not suitable for strings and varchars, but
support can be added for floats and doubles later. The supported
types are: boolean, int types, decimals, date, timestamp, and char.

Currently ZORDER has the same functionality as a simple SORT BY clause,
therefore hidden behind a feature flag: unlock_zorder. The custom
sorting with Z-ordering will be in a different commit later.

Testing:
 * Added tests for the ZORDER option for every SORT BY test.
 * Modified some tests by adding the LEXICAL option.
 * The .test workloads are temporarily put in separate test files
   in order to set up the feature flag. These tests are run from
   tests/custom_cluster/test_zorder.py which is a duplication of
   the relevant tests, but with CustomClusterTestSuite decorator.
