   Hello, I have been thinking for a long time about the readonly parameter, and I cloud't found any scenario. 
   1. If we use readonly for sharding, we will get many problems, such as which datasource should we use for DML or DQL, but It won't bring us any benefits.
   2. If we use readonly for master-slave, I think readonly is redundant, because master must be writeable and slave must be readable.
   3. If we use readonly for encrypt, I think it's redundant too.
   So, I think maybe we don't need readonly parameter in sharding-sphere.
