SHOW CREATE TABLE already outputs information for views. As a
convenience, this patch adds SHOW CREATE VIEW as an alias for SHOW
CREATE TABLE.
Switch some SHOW CREATE VIEW tests to use SHOW CREATE VIEW and add
additional test for SHOW CREATE VIEW on a table so that expected
behaviour is tested.

This changes implements support for PARTITIONED BY clauses in CTAS
statements. The syntax and semantics follow the PARTITION feature of
insert from select statements: inside the PARTITIONED BY (...) column
list the user must specify names of the columns to partition by. These
column names must appear in that particular order at the end of the
select statement. A remapping between columns of the source and
destination tables is not possible, because the destination table does
not yet exist. Specifying static values for the partition columns is
also not possible, as their type needs to be deduced from columns in the
select statement. Example:
CREATE TABLE t (a DOUBLE, b INT);
INSERT INTO t VALUES (1.5, 3);
CREATE TABLE p PARTITIONED BY (b) AS SELECT a, b FROM t;
This change also contains a fix for setting the PYTHONPATH environment
variable correctly, so you can run single python tests from the command
line.

SHOW CREATE TABLE now supports views. It returns a CREATE VIEW statement
with column names and the original sql statement.
Authorization allows SHOW CREATE TABLE to be run on view if the user has
VIEW_METADATA privilege on the view and SELECT privilege on all
underlying views and table.
E.g. "SHOW CREATE TABLE some_view" returns output of form:
CREATE VIEW a_database.some_view (id, bool_col, tinyint_col) AS
SELECT id, bool_col, tinyint_col FROM functional.alltypes

This change updates our DDL syntax support to allow for using 'STORED AS PARQUET'
as well as 'STORED AS PARQUETFILE'. Moving forward we should prefer the new syntax,
but continue to support the old. I made the same change for 'AVROFILE', but since
we have not yet documented the 'AVROFILE' syntax I left out support for the old syntax.

Adds support for "show create table", a DDL statement that outputs a DDL statement that
creates the specified table.
In general, the output DDL works in Impala, so a user can copy the output and execute it
to create the same table. However, there are a few special cases that output Hive DDL
because we do not support creating some tables in Impala: HBase tables and tables with
LZO compressed text. When we do support creating these tables in Impala, users should
be able to execute the DDL in Impala as well.
