MCOL-785 Implement DISTRIBUTED JSON functions

The following functions are created: Create function JSON_VALID and test cases Create function JSON_DEPTH and test cases Create function JSON_LENGTH and test cases Create function JSON_EQUALS and test cases Create function JSON_NORMALIZE and test cases Create function JSON_TYPE and test cases Create function JSON_OBJECT and test cases Create function JSON_ARRAY and test cases Create function JSON_KEYS and test cases Create function JSON_EXISTS and test cases Create function JSON_QUOTE/JSON_UNQUOTE and test cases Create function JSON_COMPACT/DETAILED/LOOSE and test cases Create function JSON_MERGE and test cases Create function JSON_MERGE_PATCH and test cases Create function JSON_VALUE and test cases Create function JSON_QUERY and test cases Create function JSON_CONTAINS and test cases Create function JSON_ARRAY_APPEND and test cases Create function JSON_ARRAY_INSERT and test cases Create function JSON_INSERT/REPLACE/SET and test cases Create function JSON_REMOVE and test cases Create function JSON_CONTAINS_PATH and test cases Create function JSON_OVERLAPS and test cases Create function JSON_EXTRACT and test cases Create function JSON_SEARCH and test cases Note: Some functions output differs from MDB because session variables that affects functions output,e.g JSON_QUOTE/JSON_UNQUOTE This depends on MCOL-5212
