Description:
We found out that Group Replication cannot support Serializable isolation level transactions.
Hence we want to block the transactions when it's isolation level is serializable isolation level.

To implement this, we need transaction isolation (tx_isolation information) in Tran_Context_info which is
available in Group Replication plugin code.

How to repeat:
see the code

Suggested fix:
tx_isolation should be added to Tran_Context_info
