wzhou-code edd1e21493 IMPALA-12793: Create JDBC table without data source ...

This patch changes syntax of creating JDBC table statement as
  CREATE TABLE [IF NOT EXISTS] [db_name.]table_name
  (col_name data_type
    [constraint_specification]
    [COMMENT 'col_comment']
    [, ...]
  )
  [COMMENT 'table_comment']
  STORED BY JDBC
  TBLPROPERTIES ('key1'='value1', 'key2'='value2', ...)

Both "STORED BY JDBC" and "STORED AS JDBC" are acceptable. A table
property '__IMPALA_DATA_SOURCE_NAME' is added to the JDBC table with
value 'impalajdbcdatasource', which is shown in the output of command
'show create table'.
Following required JDBC parameters must be specified as table
properties: database.type, jdbc.url, jdbc.driver, driver.url, and table.
Otherwise, AnalysisException will be thrown.

Testing:
 - Added frontend unit tests for new syntax of creating JDBC table.
 - Updated end-to-end unit tests to create JDBC tables without data
   source.
 - Passed core tests
