[feature] Transactional support

[svaroqui]

Hi, thanks for creating go-mydumper,

I don't see in code the way to get transactional snapshot

Global write lock is acquired ("FLUSH TABLES WITH READ LOCK")
Various metadata is read ("SHOW SLAVE STATUS","SHOW MASTER STATUS")
Other threads connect and establish snapshots ("START TRANSACTION WITH CONSISTENT SNAPSHOT")
Other threads connect and establish snapshots ("UNLOCK TABLES")

Is this in the roadmap or did i missed it ?

Hi,

This feature is in the roadmap(time has not yet been set for).
And welcome to try to break the version.
Thanks.
