Getting an integer return from REDIS::publish()

Currently .publish returns Result<(), Error>.
But if this can return an integer value instead of () would be better like redis-cli.
redis-cli returns an integer how many nodes get the published msg.

This is an enhancement.

Sounds good to me. As a workaround, you should be able to use the general-purpose execute method instead of publish and get the result that way.
