Description:
transaction_isolation should not be "SERIALIZABLE" in Group Replication.

How to repeat:
When starting Group Replication, the transaction_isolation should not be "SERIALIZABLE". However, this is not mentioned in any place of Chapter 17 Group Replication, especially in https://dev.mysql.com/doc/refman/5.7/en/group-replication.html. It is recommended to add this information in the document.
