   - admin set frontend config ("enable_sql_blocklist" = "true")
   
   Sqlblocklist info
   - name
   - user
   - sql
   - enable
   
   Supoort grammar
   - SHOW BLOCKLIST [WHERE name|sql|user|enable = "xxx"]
   - CREATE BLOCKLIST test_rule PROPERTIES ("user"="default", "sql"="select .* from .* join .*", "enable": "true")
   - ALTER BLOCKLIST test_rule PROPERTIES ("user"="test_user", "enable": "false")
