Feature Request: Support more efficient JSON replication

[mattlord]

Feature Description

We should add full support for more efficient JSON replication in Vitess: https://dev.mysql.com/blog-archive/efficient-json-replication-in-mysql-8-0/

Use Case(s)

The use case is around having much smaller binlog ROW events. This means less storage space on disk, less bytes over the wire, and less overhead in processing the transaction.
