wzhou-code e50bfa8376 IMPALA-12925: Fix decimal data type for external JDBC table 
Decimal type is a primitive data type for Impala. Current code returns
wrong values for columns with decimal data type in external JDBC tables.

This patch fixes wrong values returned from JDBC data source, and
supports pushing down decimal type of predicates to remote database
and remote Impala.
The decimal precision and scale of the columns in external JDBC table
must be no less than the decimal precision and scale of the
corresponding columns in the table of remote database. Otherwise,
Impala fails with an error since it may cause truncation of decimal
data.

Testing:
 - Added Planner test for pushing down decimal type of predicates.
 - Added end-to-end unit-tests for tables with decimal type of columns
   for Postgres, MySQL, and Impala-to-Impala.
 - Passed core-tests.
