IMPALA-12465: Unicode column name support
Impala depends on Hive functions for column name validation and uses
validateName() function for the same. Since Hive already supports
unicode column names, the patch just updates the column name validation
function to validateColumnName(). validateName() checks for a certain
conformance based on pattern matching standards while
validateColumnName() places no restrictions on column names at the
Metadata level.
Testing: The support is tested and cross-checked with Hive. The tests
can be found in unicode-column-name.test.
