IMPALA-4018 Part1: Add FORMAT clause in CAST()
This enhancement introduces FORMAT clause for CAST()
operator. The FORMAT clause is applicable for casts between
string types and timestamp types. The same format pattern is
accepted as what e.g. the to_timestamp() function accepts.
Usage example:
SELECT CAST('01-02-2019' AS TIMESTAMP FORMAT 'MM-dd-yyyy');
