suggest to add an parameter recursion-method to find all slave auto

hi,

suggest to add an parameter recursion-method to find all slave auto like pt-online-schema-change.

we have to avoid any lag when we do ddl on the master, if we don't have the recursion-method, we have to set all the slaves to the throttle-control-replicas.

thanks for your work.

Reason I'm suggesting this for community contribution is that we already use a solution in the form of orchestrator. orchestrator really knows the topologies and, combined with pool information, can tell us the exact list of servers to watch.

However this would be a useful feature, and not overly complicated to implement.
