MDEV-27128: Implement JSON Schema Validation FUNCTION Implementation: Implementation is made according to json schema validation draft 2020 JSON schema basically has same structure as that of json object, consisting of key-value pairs. So it can be parsed in the same manner as any json object. However, none of the keywords are mandatory, so making guess about the json value type based only on the keywords would be incorrect. Hence we need separate objects denoting each keyword. So during create_object_and_handle_keyword() we create appropriate objects based on the keywords and validate each of them individually on the json document by calling respective validate() function if the type matches. If any of them fails, return false, else return true. 2022-10-28 13:03:13 +05:30			`#ifndef JSON_SCHEMA_HELPER`
